Abstract: This research introduces a novel circularly polarized compact antenna designed for universal ultrahigh-frequency (UHF) radio-frequency identification (RFID) handheld readers for ...

Abstract: The Omniguide antenna is a new type of high-gain antenna developed for UHF-TV broadcasting. Waveguide components are employed in the design instead of coaxial line elements to increase the ...

The resulting polar plot shows the performace of the antenna at each angle, and unsurprisingly I proved to myself that a HB9CV is indeed a directional antenna. My experiment was in itself not of ...
