Time-Gating Method for V/UHF Antenna Pattern Measurement insicle an Anechoic Chamber

摘要：

Traditionally,the Time-Gating Method (TGM) is helpful in improvement of ordinary antenna pattern measurement. But for a low frequency Antenna Under Test(AUT),especially a narrow bandwidth AUT,even inside an anechoic chamber,the improvement may be very limited.This paper presentsA method of bandwidth expanding for a FD measuring system,which can realize TGM with its fast frequency sweep function. ByThis means,the interference caused by multi-path reflection can be reduced effectively,and the pattern of V/UHF AUT obtained can be more precise. The results from simulation and experiment show the efficiency of this new method.
