Abstract

Recently, the S-parameter method, which is the measurement method of the input impedance of the balanced antenna, has been proposed. In this paper, to show the possibility of the S-parameter method using jig fabricated microstrip line, the input impedance of a bow-tie antenna is examined. As a result, it is observed that the results of the S-parameter method are shown to agree with the other results at frequencies less than 3 GHz. In addition, it is thought that the main cause of the measurement error of the S-parameter method using the MSL type jig is due to the electromagnetic coupling between the antenna element and MSL.
