Abstract (en)

The present invention relates to a compact Ultra High Frequency (UHF) Radio Frequency Identification (RFID) reader antenna for handheld devices. The reader antenna has a carrier frequency and defining a volume, and the reader antenna comprises a ground element having a height, a width and a length; at least one active antenna element defining a longitudinal extension axis; and a base material having a base height, a base width and a base length. The reader antenna has a bandwidth larger than approximately 13% of the carrier frequency (frequency of operation) and a realised gain larger than 6 dBi, wherein the width of the antenna is less than 70 mm and the volume of the antenna is less than 50000 mm 3 . Furthermore, the invention relates to an RFID reader system and to use of the compact RFID reader antenna.
