A Dual-band Branch-line Coupler Using Quasi-composite Right/Left-handed Transmission Lines

A quasi-RH/LH dual-band 3 dB branch-line coupler (BLC) constructed in microstrip form is proposed. The designed BLC circuit replaces the conventional chip inductors in the coupler arms with microstrip stubs for easier circuit integration and lower fabr...
Branch-line couplers (BLC) are widely used as 90° signal dividers in microwave and millimeter-wave circuits. A BLC can provide two quadrature-phased signals from a single local oscillator for use in image rejection mixers. 1 It can be used as part of the feeding network for antennas to produce circularly...
