Duo Triangle Shaped Microstrip Patch Antenna Analysis for WiMAX Lower Band Application

This paper presents the increase in bandwidth of a microstrip antenna using a duo triangle shaped probe-fed patch. The main aim of the paper is to obtain a wideband microstrip antenna with reduced size. The dual bandwidth of 7.68% and 36.56% covering the range from 1.745-1.884 GHz and 2.229-3.226 GHz has been achieved. The dimension and position of the duo-triangular patch as well as the shifting of probe-feed coordinates have been optimized to achieve the wide bandwidth. The proposed patch antenna is designed and all the parameters are simulated on the Zeland IE3D software.
