IDEALS @ Illinois: Cavity-backed T-fed slot antenna A new method of feeding a thin cavity slot antenna with a stripline leading to a T-bar, which lies beneath or in the slot, greatly enhances the impedance bandwidth over a range of 10 to 30 percent depending on the slot width. In the past, the design parameters for the T-fed slot antenna were obtained empirically. Radiation and scattering from ferrite-tuned cavity-backed ... Radiation and scattering from ferrite-tuned cavity-backed slot antennas: theory and experiment Abstract: A three-dimensional finite-element method hybridized with the spectral/spatial domain method of moments is presented for the analysis of ferrite-tuned cavity-backed slot antennas.

A low profile, compact microstrip-to-waveguide or stripline-to-waveguide transition. The end of the waveguide is terminated in a cavity backed slot defined in a groundplane formed on a dielectric substrate.

Dual-Frequency Miniaturized Substrate Integrated Waveguide ... The cavity-backed antenna is a kind of slot antenna which can realize radiation by opening a gap in resonant cavity. Compared to ordinary microstrip antennas, cavity-backed antennas have larger front-to-back ratio and radiation gain . In recent years, the substrate integrated waveguide (SIW) circuit is always the focus of researchers. Enhanced-Gain Planar Substrate-Integrated Waveguide Cavity ... A novel substrate-integrated waveguide (SIW) cavity-backed slot antenna is proposed in this study to achieve enhanced-gain performance. The peak gain is remarkably improved with the use of an SIW cavity and metallic superstrate. Microstrip‐fed cavity‐backed slot antennas - Li - 2002 ... Two types of cavity‐backed slot (CBS) antennas fed by a microstrip line and operating at 5.8 GHz are described in this letter. One is a broadband linearly polarized CBS antenna, which can provide 34% bandwidth for a 10‐dB return loss.
