Abstract: In this paper, a compact dual-band power divider embedded with
defect microstrip with periodic loading (DMSWPL) slow-wave structure is
presented. The occupied space is effectively reduced by about 66.89% compared to the
conventional dual-band Wilkinson power divider. The structure of this power
divider and the formulas used to determine the design parameters have been
given. Experimental results show that all the features of a conventional
Wilkinson power divider, such as an equal power split, impedance matching at
all ports, and a good isolation between the two output ports can be fulfilled
at GSM-band (880 MHz ∼ 960 MHz) and DCS-band
(1710 MHz ∼ 1880 MHz) simultaneously.
