超宽带天线辐射中心的时域测量方法
Time-domain method of determining radiation centers of ultra wideband antennas
摘要
Abstract
A time-domain method is presented to determine the radiation centers of ultra wideband(UWB) antennas.Without considering the frequency of input pulses, the E- and H-plane radiation centers can be derived by measuring the time delay of waveforms in far field.When the maximal delay reaches the minimum, the reference point is the radiation center.The method is then applied to TEM horn, and its effectiveness and veracity are proved by simulating the model of paraboloidal reflector with TEM feeding horn.关键词
