Design Of A Pattern Reconfigurable Antenna For Intelligent Wi-Fi Communication And Commercial Wlan Applications
Keywords:
Pattern reconfigurable, pin diodes, omnidirectional, unidirectional and end –fire radiation modesAbstract
In this letter, a pattern reconfigurable antenna system is presented. The reconfigurable structure provides compact size, and effective isolation between different wireless standards. The proposed reconfigurable antenna is designed in ANSYS High Frequency Structure Simulator (HFSS) Software and by controlling the states of two Pin diodes; the antenna can switch between one omnidirectional mode and two unidirectional end- fire radiation modes. The experimental measurements demonstrate the return loss of -10.91 dB, -34.76 dB at frequency of 4.25 GHz and 5.76 GHz respectively. The proposed antenna is very much suitable for intelligent Wi-Fi communication and commercial WLAN applications
