Multiband Reconfigurable E shaped Micro-strip Antenna

Reconfigurable antennas are being given much focus for their versatility, compact size, low cost and high performance. Reconfigurable antennas radiate more than one pattern at different frequencies and with various polarizations providing more flexibility to antenna designers. Due to the additional degree of freedom, there is a large potential for increased system performance. The ability to switch between various systems has recently attracted special attention to reconfigurable antennas. This class of radiator can change its operating frequency, polarization or radiation pattern with the use of GaAS FET, PIN diodes and RF MEMS
