Abstract: In this paper, the bandwidth of rectangular microstrip patch antenna is enhanced by „W‟ slotted patch antenna. It can be seen that bandwidth of microstrip antenna is increased up to great extant when antenna is loaded with multiple slots. In some applications where the increased bandwidth is needed, proposed antenna is one of the alternative solution. The frequency band of proposed antenna is in between 1.45-3.25 GHz. The fractional bandwidth of proposed antenna is 76.59%. The gain of the antenna has improved up to 5.05dB, directivity 5.32dBi and efficiency 99.89%.. Proposed antenna is suitable for WiMAX/GPS/WLAN applications. The proposed antenna has been designed on glass epoxy substrate having = 4.2 and the design frequency of proposed antenna is 2.2 GHz. The proposed W slotted microstrip antenna is fed by 50Ω microstrip feed line.

Keywords: Slot loaded, enhanced bandwidth, compact Microstrip (MS) Patch, radiation pattern, gain, 50Ω feed line.
