Microstrip patch antennas can be fed by number of techniques. These techniques can be categorized as contacting and non-contacting.This model represents the microstrip antenna by two slots of width W and height h, separated by a transmission line of length L. The microstrip is essentially a... Cavity-backed slot antennas for wireless portable… Conventional cavity-backed slot antenna (CBSA) consists of a resonant metal cavity, having a slot, fed by a probe. The cavity for such an antenna requires large space. This paper presents an alternative to such antennas by using a compact non-resonant cavity where the slots are excited.

WIDEBAND CAVITY-BACKED CROSSED DIPOLES FOR CIRCULAR POLARIZATION Xue Bai and Shiwei Qu* School of Electronic Engineering, University of Electronic Science and Technology of China (UESTC), Chengdu 611731, China Abstract|A novel circularly polarized cavity-backed antenna (CBA) excited by crossed bowtie dipoles is presented in this paper. It is fed Dual-Feed Cavity-Backed Slot Antennas - tandfonline.com papers, it can be seen that dierential-feed microstrip antenna can achieve wider bandwidth than the single-feed counterpart. However, the microstrip element suers from the inherent limitation of narrow impedance bandwidth. Microstrip-fed cavity-backed slot antennas have the advantages of wider bandwidth, less interaction via surface
A flush-mounted antenna assembly (10) including a generally rectangular, conductive, box structure (11) open along one face to form a cavity. Within the cavity a pair of mutually orthogonal dielectric plane surfaces (13) (14) in an "egg …
