A Pattern and Polarization Reconfigurable Antenna For WLAN Application
A pattern and polarization reconfigurable antenna (PPRA) for WLAN applications has been presented in this paper. The proposed antenna has a square ring patch fed by T-shaped microstrip line through gap coupling on upper layer. A defective ground surface has been deployed at the ground for increasing the gain of the antenna. Two diodes PD1 and PD2 have been incorporated in the upper diagonal gap of square ring to achieve polarization reconfigurability and two more switches PD3 and PD4 have been inserted in ground plane to achieve pattern diversity. Depending on diode (ON/OFF) conditions the PPRA can switch to different polarization states viz. horizontal, vertical, S(−45) and Z(45) linear polarization. Also it is able to switch its pattern by 180° in E-plane. Extensive simulations have been performed in CADFEKO for antenna design and optimization. HPND-4005 PIN diodes equivalent circuit for ON and OFF state has been used for simulation purpose. The proposed antenna is able to cover the entire (2.412-2.484) GHz band for IEEE 802.11b/g/n standard.
