摘要： A dual band, stacked microstrip antenna produces circular polarization. A two-layer, 90° microstrip coupler is mounted to a hi-band patch and a lo-band patch and provides two inputs to the antenna to excite two orthogonal linearly polarized radiation patterns in quadrature. The coupler outputs are connected to the antenna by two conducting pins that connect directly to the groundplane of the lower patch. The coupler uses the hi-band patch as a groundplane and is transparent to the radiation from the antenna. An antenna input connector is connected to the coupler input by means of a coaxial line through the center of the antenna. The isolation port is terminated in a surface mounted 50-ohm resister to ground through a quarter wave length open transmission line.
