Abstract

A new antenna design method with high efficient characteristics is proposed by measuring input impedance of a radiative resonator. By means of a simple de-embedding method, the resonant frequency and input impedance are measured for antenna resonators. Retaining the resonant antenna characteristics, an impedance-matched feedline can be designed. In order to verify the validation, the patch antenna has been implemented with the proposed method. From the experimental results, the proposed antenna design has presented well matching property, a higher antenna gain, and higher radiation efficiency, compared to a reference patch antenna implemented by a conventional design method.
