Optimal Design of a Broadband Matching Network for an Electrically Small Antenna
An optimal design approach which combines the real frequency method and the direct numerical optimization is used to design a broadband matching network for an electrically small antenna.According to the characteristic of electrically small antenna,a network topology which improves the electrically small antenna’s efficiency observably is designed with two methods respectively,and the design result is computed and validated with simulation software.Finally,the two methods are compared in the paper.Results show that the VSWR of the antenna is below 2.5 and its efficiency is above 30％ in the pass band by optimal design,that is,the performance of the antenna is improved by a wide margin.
