Antenna for WLAN and Wimax Application
In this paper, the authors have presented the use of reconfigurable micro strip patch antenna elements in adaptive arrays. Adaptive array systems are generally referred as smart antennas. The adaptive array have the potential to reduce noise, increase the signal to noise ratio and enhance system capacity. Similarly the reconfigurable antenna has the capability of adapting properties to achieve selectivity in frequency, bandwidth, polarization and gain. So the combination of both reconfigurability and adaptivity in a single array is investigated. As the different standards have different requirements and use different frequency bands mainly around 2.4GHz to 5GHz, the RF circuits and antennas designed for each system must be able to work at different frequency bands.
