部は回転屈折機構を介して保持する必要がある。2. Description of the Related Art Generally, a rod-shaped antenna element is used as an ultra-high frequency antenna for this type of radio telephone. When the wireless telephone is used as a portable device, it is required to hold the base end portion of the rod-shaped antenna element via a rotary bending mechanism. That is, the rod-shaped antenna element is housed in the wireless telephone case when not in use, but when used, it must be pulled out of the case and then bent and held at right angles to the pulled-out direction. There is. Also, when the wireless telephone is in a sideways state in a car, etc., it is rotated by a predetermined angle around the antenna element insertion hole of the wireless telephone case to change the azimuth angle of the antenna element bent in a right angle direction. Must be set. In order to make such an operation feasible, it is necessary to hold the base end portion of the antenna element through a rotary bending mechanism.

In the past, metal was used exclusively. That is, conventionally, in order to electrically connect the antenna element to the input / output end of the wireless telephone, the element supporting base having the antenna element shaft supporting portion and the guide pipe are formed of metal.

た。The axial support for refracting the antenna element has a structure in which the base end of the antenna element is held by the support of the joint member. That is, the antenna element is held at a predetermined angle by the frictional force between the base end portion of the antenna element and the joint member support portion.

程度の性能しか得られないという問題があった。The above-mentioned conventional ultra-high frequency antenna for a wireless telephone has the following problems. That is, since the components of the rotary refraction mechanism are made of metal, interposing this rotary refraction mechanism in the antenna mounting part increases the stray capacity between the earth and ground, causing loss of radiated energy and impedance. There is a problem in that matching becomes impossible and, consequently, wideband characteristics cannot be obtained, and only performance that can finally secure a function as a receiving antenna is obtained.

う欠点があった。Further, since the shaft supporting portion for refracting the antenna element is configured to maintain the supporting angle of the antenna element by frictional force, the durability is poor and the supporting force is lost in a relatively short period. The antenna element cannot be kept stable at a required supporting angle. In order to withstand long-term use, the diameter of the support portion that holds the base end portion of the antenna element under pressure needs to be at least about 8 mm. However, such a size of the supporting portion is not preferable because the metal portion such as the constituent member of the rotary refracting mechanism is further increased. Further, the rotating portion for changing the azimuth angle of the antenna element has many components, and further, a sufficiently large locking force cannot be obtained, so that there is a drawback that the antenna azimuth angle cannot be easily and accurately set.

The antenna element support is highly durable, the element holding angle can be kept stable over a long period of time, and it can be manufactured in a small size.

構成でありながらアンテナ方位角を容易かつ適確に設定
することが可能となる。Since the main member of the rotary refraction mechanism interposed in the antenna mounting portion is made of resin, the stray capacity between the earth and the ground is small, the loss of radiant energy is small, the impedance matching is easy, and the broadband characteristics are wide. As a result, the function as a transmission / reception antenna is fully exerted. In addition, since the antenna element is configured to hold the antenna element at a predetermined angle by means of the element angle setting means, it is more durable than the conventional configuration that depends on frictional force, and the required element holding angle can be maintained for a long period of time. It can be kept stable over time. Further, since the diameter of the supporting portion of the joint for holding the base end portion of the antenna element under pressure is about 4 to 5 mm, the metal portion in the rotary bending mechanism is further reduced. For this reason, it is preferable in terms of eliminating the influence of stray capacity, and since the diameter of the support part is small, it is possible to reduce the diameter of not only the rotating and refracting mechanism itself, but also the guide pipe, etc. It becomes possible to do. Further, in order that the cylindrical support base made of resin is intermittently rotatably held in the holder made of resin, an uneven elastic contact portion is formed between the outer peripheral surface of the cylindrical support base and the inner peripheral surface of the resin holder. Since the antennas are arranged so as to face each other along the circumferential direction, the antenna azimuth can be set easily and accurately with a simple structure.

Thus, when the cylindrical support base 14 is inserted into the resin holder 11, the convex portion 11c is engaged with the concave portion 14c and the partition wall 14d is engaged with the cut groove 11d. Therefore, both are stably held at a predetermined rotation angle. Cylindrical support base 14
If is forcibly rotated, the engaging position of each of the above parts is shifted by one step. Then, the engagement is performed again at the displaced position, and the rotational angle is stably maintained. Next, the operation and action of the ultrahigh frequency antenna of the present embodiment configured as described above will be described.

る。When the antenna element 1 is projected outside the radio telephone case 2 during use, first the antenna element 1 is pulled out from the radio telephone case 2 as shown by arrow A and then as shown by arrow M. The light is refracted in a direction perpendicular to the direction in which it is pulled out. Then antenna element 1
The ball 16 in the element support angle setting means 30 allows the antenna element 1 to rotate while repeating engagement and disengagement with the cutout portions 21a, 21b, and 21c of the base end portion 21. When the antenna element 1 is rotated, for example, by 90 ° and refracted in a direction perpendicular to the pulled-out direction, if the refracting operation of the antenna element 1 is stopped, the ball 1 is placed at that position.
Reference numeral 6 denotes notches 21a, 21 of the base end 21 of the antenna element 1.
It engages with one of b and 21c, for example, 21c. Therefore, the antenna element 1 is stably held at the above angle.

Along with this, the cylindrical support base 14 rotates about the axis, and the partition wall 14d of the cylindrical support base 14 is moved by one step while pushing up the convex portion 11c of the resin holder 11 by this rotation operation. At this time, the cylindrical portion of the resin holder 11 is
The cut groove 11d works to elastically deform smoothly to allow the displacement of the protrusion 11c. Thus, the convex portion 11c and the concave portion 14c are joined again at the position displaced by one step. By repeating this operation, the cylindrical support base 14 intermittently rotates inside the resin holder 11 and is stably held at the rotated position. Thus, the azimuth angle of the antenna element 1 in the state of being bent in the perpendicular direction is changed and set.

That is, the antenna element 1 is housed in the case 2 by extending the antenna element 1 as shown by the arrow N and then pushing it into the case 2 as shown by the arrow B. At this time, the element support angle setting means 30
The operation of setting the support angle of the antenna element 1 and the intermittent rotation holding operation of the cylindrical support base 14 and the resin holder 11 are performed in the same manner as the operation of pulling out the antenna element 1.

Since it is configured to hold at a predetermined angle, it is more durable than the conventional structure that depends on frictional force, and the required element holding angle can be kept stable over a long period of time. .. In addition, since the diameter D of the support portion of the joint 15 that holds the base end portion of the antenna element 1 in a pressure-fitting state is about 4 to 5 mm, the metal portion in the rotary bending mechanism is further reduced. For this reason, it is preferable in that the influence of the stray capacity is eliminated, and since the diameter D of the support portions 18 and 19 is small, not only the rotary bending mechanism itself but also the guide pipe 3 and the like can be downsized. As a result, the entire antenna can be manufactured in a small size.
