  • Abstract
    This paper presents, for the first time, the design of a branch-line coupler that can operate at two arbitrary frequency bands. Moreover, design equations of the coupler with sub-optimum performance is analytically derived. The proposed circuit also features compact size, planar structure and low-loss. For verification, both simulated and measured results of a microstrip branch-line coupler operating at 900/1500 MHz are shown.
