A Compact Frequency Reconfigurable Metamaterial Based Antenna for Wireless Applications
This paper presents a frequency diversity microstrip antenna inspired by a metamaterial structure that resonates at single or multiple frequency bands for wireless applications. The metamaterial is designed to have multiple double negative bands overlaps with the antenna wideband reflection coefficients. Two ideal PIN diodes are inserted in the metamaterial portion that facilitates having a different frequency band of operation by altering their states. The proposed antenna can work on single, dual, or triple spectrums. Antenna characteristics are investigated to ensure the wellness of the design. It has a peak gain of 4.7 dB and its radiation efficiency can reach 98.78 %.
