| 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 a SMA connector installed on the jig for the meas-urement is experimentally examined. Two kinds of jigs with a different direction of the installed connector are fabricated, 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, it is observed that the difference appeared to measured values in the frequency of about 7 GHz or more by turning around the connector. | |
