Abstract

A dual‐band branch‐line quadrature coupler with extended bandwidth using simple three‐section branch line is presented.This proposed design exhibits larger bandwidth than existing dual‐band designs reported in previous literature. A dual‐band branch‐line coupler was designed and measured to give 34.5 and 16.4% bandwidth in the lower band and upper band, respectively, for an amplitude imbalance less than 1 dB. The achieved bandwidth is wide enough to cover wireless local area network and wideband code division multiple access applications. © 2010 Wiley Periodicals, Inc.

## 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 form
