Three-port rectangular microstrip unequal power divider and coupler

Abstract

A new configuration of a three-port rectangular microstrip power divider and coupler has been proposed. It can easily implement unequal power division of a large ratio, i.e., the power coupled to the third port can vary from -3 to -26 dB. The configuration has been analyzed using a transmission-line model, as well as method-of-moments-based software. (C) 2001 , Inc.
