The antenna circuit board 3 has a plurality of radiating elements 5 arranged at regular intervals in the vertical and horizontal directions and a feed line 6 connected to the radiating elements 5, a dielectric 2b, and a plurality of slots 7 for radio wave radiation. There is known a planar antenna in which the slot plate 4 and the slot plate 4 are stacked in this order so that each slot 7 is directly above each radiating element 5. Such an antenna is
The upper and lower sides of the power feeding line 6 are sandwiched between the ground conductor 1 and the slot plate 4 and electrically shielded, so that unnecessary radiation from the branched portion and the bent portion of the power feeding line 6 can be suppressed, and the efficiency can be improved. It is a thing.

As shown in (c), a feeding line is connected to the edge of a circular radiating element for use.

するという課題も発生する。However, in reality, the antenna installation angle rarely coincides with the transmitting and receiving polarization directions. In such a case, the antenna installation angle is changed. It is normal to do so. However, changing the installation angle of the antenna has a problem that the equipment becomes large and the installation place is wide. Therefore, there is also an attempt to change the excitation angle of the radiating element of the antenna. In this case, the arranging angle of each radiating element is changed. The space between the radiating elements becomes narrower, and it becomes difficult to provide a feed line. Even if they can be arranged, the distance between the feed line and the radiating element becomes narrow, and the electromagnetic coupling between the feed line and the radiating element makes it impossible to maintain the high efficiency characteristic of such a planar antenna. In addition, since power is fed from the same direction, radiation of higher modes orthogonal to the polarization direction becomes polarized radiation (cross-polarization), and unnecessary radiation occurs in the case of transmission, or in the case of reception. Also causes a problem that the cross polarization ratio is reduced.
