ELECTRICALLY SMALL TUNABLE SPLIT RING RESONATOR ANTENNA
Xiaoyu Cheng, David Senior, James Whalen and Yong-Kyu Yoon
A tunable SRR antenna is investigated both theoretically and experimentally. The proposed antenna has a variable radiation frequency from 1.81 GHz to 2.14 GHz with a tuning voltage between 0 and 9.5V. Simulated data show good agreement with measurement ones. Besides tuability, the proposed antenna has achieved a dimension reduction by 59.3 % compared with the monopole counterpart.
