Microstrip fed slot antenna backed by a very thin cavity
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 , 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 ...

A microstrip antenna system having one or more conductively isolated resonantly dimensioned radiator structures disposed less than about one-tenth wavelength above a ground plane is nonconductively coupled to an intermediate layer of … Antenna Designing | Metamaterial | Antenna (Radio) CRA is an evolution of the antenna proposed by Roederer in 1990 . Antenna is a rhomb shape microstrip over a ground plane as shown in Figure 1. Circular right or lef polarization depends on feed and load position. Radioengineering - April 2018, Volume 27, Number 1 [DOI: 10… The monopole antenna is modified using microstrip transition in the feedline and block with a triangular-shape slot on each side of the circular patch to produce wider impedance bandwidth with better return loss. US5519408A - Tapered notch antenna using coplanar waveguide… A radiating tapered notch antenna (sometimes known as a Vivaldi antenna) is fed by a section of slotline, which in, turn is fed by a coplanar waveguide. The transition from the unbalanced coplanar waveguide to the balanced slotline is …
