Dual Band H Shaped Rectangular Microstrip Patch Antenna for WLAN/WiMAX/Bluetooth Applications
In this paper, the bandwidth of rectangular microstrip antenna is enhanced by 'H' shaped rectangular microstrip patch antenna. In some applications where the increased bandwidth is needed, dual frequency patch antenna is one of the alternative solutions. The proposed antenna has dual frequency band. In first frequency band (1.63-1.79 GHz) the fractional bandwidth is 9.35% and in second frequency band (2.4-3.34 GHz) the fractional bandwidth is 33.03%. The gain has been improved up to 3.82dBi, directivity 3.87dBi and efficiency 98.91%.
