Cavity backed slot antenna theory

The present invention is directed toward a dual linear or circular polarized antenna comprised of two orthogonally linearly polarized radiative elements. More specifically, the present invention is for a slender slot-dipole antenna, where …

Theory and experiment of the hemispherical cavity-backed… Theory and experiment of the hemispherical cavity-backed slot antenna IEEE Transactions on Antennas and Propagation Institute of Electrical and Electronics Engineers 0018-926X 10.1109/8.718580. A conformal cavity-backed supergain slot antenna A conformal supergain slot antenna is presented in this paper, which comprises a thin substrate on the top broad wall of a shallow metallic cavity. Three slots with different lengths are etched out at suitable positions of the cavity wall to enhance the bandwidth as well as to achieve the supergain. A Compact Wideband Dielectric Resonator Antenna with a…

Simulated gain patterns of the SIW cavity-backed slot … 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. The superstrate comprises a single rectangular slot window and two...
