Abstract
This paper presents a new quadrature coupler, which exhibits harmonic suppression and bandwidth enhancement simultaneously. The proposed coupler is formed using a circular sector patch and an array of mushroom cells. One design has been implemented to investigate the capabilities of the structure. The simulation and measurement results are in good agreement with each other. The coupler exhibits a bandwidth of 36.5% with high suppression level up to second harmonic frequency.
