A Multiband Frequency Reconfigurable Rotated-L Slot Antenna

Abstract

A multiband frequency reconfigurable rotated-L slot antenna is presented. The antenna is switchable between 4.61-6.20 GHz at nine different frequencies and capable to operates multi frequency at a time. The proposed antenna has a microstrip patch and two rotated-L slots, one slot is at patch and other is at ground plane. The two p-i-n diode is used in the ground plane rotated-L slot to achieve multi frequency agility. Results such as return losses, radiation patterns, gain and bandwidth are used to demonstrate the performance of the proposed antenna.
