Previous dual-band quadrature branch line couplers were either narrow band or had phases in the two bands that are not aligned. A vestigial dual-band quadrature branch line coupler is presented that is phase aligned and with one band that is broad, making it ideal for WLAN and other dual-band applications. © 2008 The Institution of Engineering and Technology.
