Abstract (in Japanese) (See Japanese page) 
(in English) Recently, the S-parameter method using a vector network analyzer and a measurement jig instead of a balun has been pro-posed whereby the differential input impedance of a balanced fed antenna can be found. Because the balun is not used, it is possible to measure impedance over a wide bandwidth. However, when measured frequency rises, it is known that measure-ment accuracy decreases because the influence of the jig cannot be disregarded for the measurement. In this report, to im-prove the measurement accuracy of S-parameter method, the influence of the substrate edge connector installed on the jig for the measurement is experimentally examined. The jig is fabricated by two kinds of edge connectors, and the input impedance of a dipole antenna is measured by the S-parameter method. The measured values are compared with the available theories by King and the calculated values that used two kinds of FDTD models. As a result, the jig using the edge connector with four support to fix to the substrate edge showed that the measured error is observed above the frequency from 6 to 7 GHz.
