This paper presents a direct coupled slotted microstrip antenna with enhanced antenna gain and wider bandwidth. A typical design has been implemented and the results are presented and discussed. The different antenna geometries are simulated through IE3D Zeland simulation software for the comparative analysis of bandwidth. The proposed antenna has dual frequency band having dual bandwidth 3.38 % (1.392–1.44 GHz) and 69.5 % (1.733–3.58 GHz) which is suitable for WLAN/GPS/WiMax applications.
