摘要：
A novel compact size broadband quadrature hybrid coupler based on a planar artificial transmission line which can be used for WLAN application at 2.4 GHz is presented. The planar artificial transmission line is composed with both a dual transmission line and the Pi-model technique. The occupied size of the proposed broadband hybrid coupler is merely 47% of the size of a conventional design. The compact size coupler demonstrates well-behaved wideband response and good agreement with measurement.
