Design and Development of a Compact Triple-Band Microstrip Patch Antenna Loaded with Shorting Pin.

Abstract

A single layer coaxial probe fed compact shorted patch antenna capable of triple band operation for GSM, ISM and WiMax application has been designed, fabricated and analyzed. The designed antenna generates three separate resonances to cover 1.9 GHz DCS, Bluetooth and WLAN (2.4 GHz), 3.5 GHz WiMax bands while maintaining a small overall size of 36*28*1.6 mm3. A prototype is fabricated and experimental results show good radiation characteristics over the operating bands.
