Microstrip fed slot antenna backed by a very thin cavity

By Editor

Compared with basic microstrip patch antennas, wide-slot cavity-backed antenna, proposed by Hirokawa, Arai, and microstrip-fed slots have the advantages of wider bandwidth, less Goto [10], was fed by a metallic feed line of negligible radius interaction via surface waves, and better isolation from feed net- matched with the coaxial cable of 50 ⍀.

Design and experimental verification of dual-Fed, self Design and experimental verification of dual-Fed, self-diplexed cavity-backed slot antenna using HMSIW technique -based cavity, loaded with a slot and microstrip feedlines. A radiating slot is etched on the upper metal cladding of the HMSIW cavity which splits the cavity into two sections. ... By finely tuning the antenna dimensions, a very ... A cavity-backed coplanar waveguide slot antenna array A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz.

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 …

In this paper, a novel compact dual-band and dual-polarized CSRR-fed SIW cavity-backed fractal patch antenna, which aims to work simultaneously for wireless energy harvesting and communication, is proposed and analyzed. It is shown that the combination of fractal geometries and the CSRR feed is effective in the design of compact SIW antennas. Cavity Backed Patch Antenna - weSRCH Description: Cavity backing of the conventional rectangular microstrip antenna is being proposed. The proposed antennas have been simulated. Improved values of Gain has been obtained from the proposed antenna. Results obtained for the cavity backed and without cavity-backed antenna has been compared.
