Proximity Fed Broadband 120 0 Sectoral Microstrip Antenna

Proximity Fed Shorted 1350 Sectoral Microstrip Antenna

Compact shorted 1350 Sectoral microstrip antenna derived from 2700 Sectoral microstrip antenna is proposed. On thicker air substrate (h > 0. 1?0) it yields bandwidth of more than 350 MHz (35%). To increase the bandwidth, its rectangular slot cut variation is proposed. The slot reduces the resonance frequency of higher order TM1/4,1 mode of the shorted patch and along with fundamental TM1/4,0 mo...

Broadband Shorted Plate Proximity Fed Rectangular Microstrip Antenna

Proximity fed Broadband Microstrip Antennas

The broadband microstrip antenna is realized by fabricating the patch on lower dielectric constant thicker substrate in conjunction with proximity feeding technique. Using thicker substrates, a formulation for an edge extension length and design guidelines for strip dimensions in proximity fed broadband antennas, are not available. In this paper, first by designing suspended rectangular and cir...

Broadband Gap-coupled Shorted 60° Sectoral Microstrip Antenna

The compact variation of equilateral triangular microstrip antenna, a shorted 600 Sectoral microstrip antenna is discussed. The proximity fed shorted 600 Sectoral microstrip antenna is proposed which gives simulated and measured BW of more than 700 MHz (>60%). To increase the bandwidth and gain, gap-coupled configuration two Shorted 600 Sectoral patches is proposed. It yields simulated and meas...

Broadband Slot Cut Gap-coupled Proximity fed E-shaped Microstrip Antenna

Bandwidth of proximity fed E-shaped microstrip antenna has been increased by gap-coupling pair of rectangular slot cut rectangular microstrip antennas along its radiating edges. The patch and slot dimensions were optimized to cover 800 – 1200 MHz frequency band. In this paper, a detail analysis to study the effects of slot and patch dimension on the broadband response in desired frequency band ...
