A dual linearly polarized endfire antenna, excited by an E-plane 180° 3 dB hybrid coupler, is reported for millimeter-wave applications. The radiator is constructed by two stacked open-ended substrate integrated waveguides (SIWs). A slope-shaped slot is employed to the common metallic layer of the two SIWs, operating as a polarizer.Lange Coupler Branchline Coupler Directional Coupler 180 Deg.Hybrid C. Mw.

Broader bandwidth can be obtained by cascading two lumped-element sections. This technique is applicable to other distributed devices such as the 90 degrees branch-line hybrid and the ...Hybrid couplers are four-port devices that split the incident power signal into two output ports. The signals at the outputs are attenuated by three decibels (3dB) and have a 90 degree phase difference with respect to each other. Three decibel attenuation means that 50% of the .Based on the modified TRD coupler and combined with the coupled line contra-directional (CTD) coupler, a novel coupled line 180° hybrid is constructed.
