A NEW METHOD FOR DESIGNING CIRCULAR WAVEGUIDE PHASER WITH SMALL ELLIPTICITY
-
摘要: 本文介绍设计小椭圆度的圆波导移相器的新方法。该方法在理论上虽不严格,但在工程应用上作为处理某些难解决的相移问题却是有效的。在4GHz频段500MHz带宽内,90相移量的理论值与实测值间的最大差异仅为1.4。

Abstract: A method for caleulating the phase shift of a dielectric slab loaded circular waveguide with small ellipticity is described. It gives an excellent result for engineerring purposes, although it is not rigorous in theory. The maximum difference between the calculated and measured results for a 90 phase shift is only 1.4in 500 MHz band-width at 4GHz. -
