Summary:
The reconfigurable antennas have drawn lots of attention in the wireless communication systems especially for cognitive radio application, radar system, and multi-frequency communication. As a front component in wireless communication system, the tunable wideband frequency and good radiation pattern are required [1]. The advantage of a reconfigurable antenna is can reduce any unfavourable effects resulting from co-site interference and jamming [2]. The reconfigurable antenna might be having diversity in frequency [2, 3], polarization [4], radiation pattern [5] and sometimes two or more diversities with the same antenna [6]. The reconfiguration can be implemented through the PIN diode switches [2, 4], MEMS [6] or varactor diodes [3]. However, electronic tunability using PIN diode is more frequently used because of its efficiency and reliability especially in dynamic bandwidth allocation.
