Abstract

The design and analysis of a novel dual‐band equal‐split Wilkinson power divider are presented in this article. The proposed structure has no extra lumped and distributed elements. Moreover, the measured bandwidth of the proposed structure is more than 240 MHz for S~11~<‐20 dB. The formulas used to determine the design parameters have been given. Closed‐form design equations are derived using Z‐parameters matrix. For verification, a microwave power divider operating at 1 and 2.6 GHz is fabricated, the experimental results show that the designed power divider fulfills all the features of a conventional Wilkinson power divider, such as an equal power split and impedance matching at ports. © 2009 Wiley Periodicals, Inc.

## Abstract An experimental investigation of a novel compact Wilkinson power divider incorporating a 1‐D PBG slow‐wave structure, in the form of perforation on the curved microstrip line itself, is presented. The size of the power divider is reduced by 22% due to the slow‐wave effect. The inclusion
