Frequency Reconfigurable Complementary Electric LC Resonator Antenna

Abstract

This paper presents the design of a frequency reconfigurable Metamaterial (MTM) antenna based on complementary electric-LC (CELC) resonator. The proposed antenna design consists of slot-loaded ELC on the ground plane as the main radiating element and excited by a microstrip line. By inserting two PIN diodes switches, it can switch to three frequency bands of operation. The antenna has been simulated using the CST Microwave Studio software tool. The simulation result shows that the proposed antenna is capable of reconfiguring up to three different frequencies which are 2.42 GHz, 2.56 GHz, and 2.70 GHz.
