Design of passive beam-scanning monopulse leaky-wave antennas for direction finding in UHF RFID
We demonstrate the design of frequency-scanning monopulse leaky-wave antennas in planar technology, which can be used for low-cost direction finding in passive UHF RFID systems. It is highlighted the importance of the selected material, providing guidelines to cover a certain field of view. We report a 120° coverage using a high-permittivity substrate, and hopping between RFID channels from 902 to 928 MHz.
