Abstract

Here we design a compact size air suspended microstrip line fed patch antenna with semi circular cut on non radiating edge. This antenna has wide band width. The fractional bandwidth is approximately 20% of 1.82 GHz. Without semicircular cut on each non radiating edge its aspect ratio is greater then 2 by which cross polarization occur, but using this technique the aspect ratio maintain up to 1.04 which avoid cross polarization & broaden more impedance bandwidth by air suspended antenna.
