A CPW Fed E-Shaped Reconfigurable Antenna With Frequency Diversity
A new CPW fed E-shaped reconfigurable Antenna with frequency diversity is designed and analyzed in this paper. The basic antenna consists of CPW fed E-shaped Patch antenna which operates at 5.8GHz which falls in IEEE 802.11 WLAN/RFID applications. The reconfigurability in frequency is obtained by connecting the switches in basic antenna by use of PIN diodes. By controlling the switches the antenna can be operated at three different frequencies namely 8.5GHz, 6.18GHz and 8.76GHz. The return loss of -28dB, -28.2dB,-33.07dB and -38.17dB are observed at 5.8GHz, 8.5GHz, 6.18GHz and 8.76GHz respectively.
