Open publisher page 1 citations

Abstract

A high gain cylindrical resonant antenna is proposed in this paper. The antenna is fed by a coaxial line. Its work frequency can be adjusted by filling different dielectric inside the antenna. The performance of the antenna is optimized by simulation, and the prototype is fabricated. The measurement results are compared with the simulation results to validate the performance. The results show that the proposed antenna has good directivity and gain at frequency range from 1.28 GHz to 1.4 GHz. With internal water filled, the work frequency of the antenna can reduce to 200MHz, with 11% relative bandwidth.
