摘要：Microstrip patch antennas are most widely used antennas because of its application in mobile phones, low cost, ease of fabrication etc. These antennas are planar, have applications in defense, aircraft and have so many shapes like rectangular, circular, triangle, square etc. Circular shape is one of the famous shapes among all. In CMPA as frequency increases the radius of circular patch decreases. In this paper circular patch designed at 900MHz & the important parameter like reflection coefficient, VSWR, polar plot, gain (IEEE) calculated. With application of air gap between dielectric there is variation in resonant frequency of the antenna. The frequency get shifted from 900 MHz to 2.712, 2.2298, 2.268 GHz. If the radius calculated for increased frequency the radius is small in comparison of 900MHz frequency that means antenna get compact. The comparison of all four designs has been done. Hence in this paper CMPA get compact in terms of frequency using air gap.
