A new configuration of a three-port rectangular microstrip power divider an
d 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 John Wiley &
