Experimental Results of Compact Dual Frequency Microstrip Slot Antenna

Owing to the compactness of communication equipment, designs for reducing the size of the microstrip antenna have received much attention in today’s era. Keeping in view of this, a microstrip slot antenna is designed and fabricated on FR 4 dielectric material suiting for various communication applications such as WiMax, RADAR, fixed satellite services, WLAN, satellite communication applications. The practical results show that the proposed antenna, having compactness of 27 % has a bandwidth of 180 MHz (VSWR < 2:1) with moderate gain of 5.20 dB showing omnidirectional radiation patterns across the whole operating frequency band.
