We propose a method for increasing the bandwidth of a substrateintegrated-waveguide (SIW) cavity-backed antenna with taper-based microstrip SIW transition feeding. For radio transmission, a circular slot is etched on top of the SIW cavity. For optima

This article introduces an ultrawideband antenna with stable phase center and circular polarization. The proposed antenna is a low-profile cavity-backed spiral antenna measuring $58\times 58\times 50$ mm3, where the cavity is partially filled with an

A conical cavity-backed antenna with embedded multiple quarter-wave resonators (multiple QWRs) is proposed. The 3-dB axial ratio bandwidth (ARBW) of a cavity-backed antenna is limited by cavity resonance, undesired cavity current, and circular polari
