A microstrip slot antenna is very small and lightweight still it has the problem of back radiation due to which power loss occurs and the SAR increases. To reduce the back lobe a technique introduces i.e. aperture coupled microstrip slot antenna which reduces the back lobe as well as increases the bandwidth of the antenna.

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 ⍀. IDEALS @ Illinois: Cavity-backed T-fed slot antenna Like thin microstrip patch antennas, cavity-backed slot antennas typically have a narrow impedance bandwidth of 1 to 6 percent of center frequency, which limits their usage. 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 ...

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.

Microstrip-Fed Dual-Frequency Annular-Slot Antenna Loaded by Split-Ring- Slot.Abstract: A compact dual-band annular-slot antenna loaded by a concentric split-ring- slot is presented. A stepped microstrip feedline enables the control of the coupling and provides good matching. Design and Analysis of Horn antennas are very easy fed with waveguide, but it can be fed also by a coaxial cable and a proper transition.The Microstrip Patch Antenna is a single-layer design which consists generally of four parts (patch, ground plane, substrate, and the feeding part). A Large Bandwidth T-shaped Microstrip-fed Ground Plane … In a conventional microstripline-fed slot antenna, a narrow rectangular slot is cut in the ground plane, and the slot is excited by a microstrip feedline with either a short 4 or an open 5 termination. With this feed configuration, a good impedance match has been achieved for a narrow slot, and an impedance... Overview of Microstrip Antennas | Thin Substrate…
