In this paper, a compact omnidirectional circularly polarized (CP) cylindrical dielectric resonator antenna (DRA) is presented. The DRA is excited in its TM01δ mode by a probe located at the center, giving linearly polarized (LP) omnidirectional radiation patterns. Four interleaved strips serving as a wave polarizer are placed on the top of the DRA. By tuning the strips, the LP fields can be changed...
The compact wideband circularly polarized (CP) hollow dielectric resonator antenna (DRA) with an embedded vertical feed network is investigated. A printed quadrature hybrid coupler is used as the feed network. Since the footprint of the feed network is small, the design can be very compact. For demonstration, a hollow cylindrical CP DRA was designed at ∼2.4 GHz for WLAN applications. The reflection...
