Microstrip fed slot antenna backed by a very thin cavity

By Admin

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 ... Abstract: A dual-fed low-profile self-diplexed slot antenna is proposed for 5.2/5.8 GHz applications. The antenna mainly comprises a half-mode substrate integrated waveguide (HMSIW)-based cavity, loaded with a slot and microstrip feedlines. US4054876A - Cavity antenna - Google Patents A cavity antenna having an aperture which may be mounted flush to the gro plane. A chamber positioned above a rectangular resonant cavity allows the antenna to achieve normal bandwidth and normal gain with a very thin cavity depth. 2818 IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL ...
