内容記述 | The reflection method is known as an accurate and simple method for measuring the radiation efficiency of a small antenna. Two big problems arise in the measurement of the radiation efficiency using this method, in which a straight waveguide and two sliding shorts are implemented. To reduce a measurement time, one sliding short is foced, whereas the other sliding short can be moved. To improve the accuracy, we can set an antenna under test at the middle of two sliding shorts, where the magnitude of the standing wave is locally maximized in the waveguide. When a sliding short is fixed, the efficiency falls into negative territory at some frequencies. We analytically consider the drops using an equivalent transmission line model for the reflection method. Also, we derive overall efficiency for above two cases and examine the way to measure the efficiency with no drops. | |||||
