This paper presents analysis and design of a dual band
Wilkinson power divider for wireless applications. The design is
accomplished by transforming the lengths and impedances of the
quarter wavelength sections of the conventional Wilkinson power
divider into dual band T-shaped sections. Simple design equations
for the basic geometry are given. The designed dual band
Wilkinson power divider structure is analyzed using a full wave
electromagnetic EM simulator and then realized for the Global
system of mobile communications (GSM) bands (925-960 MHz) and
(1930-1960 MHz). The computed and the measured S-parameters
are in a very good agreement.
