Six-port junction/directional coupler with 0/90/180/270 amp;deg; output phase relationships

摘要

A single six-port device which can be used to excite antenna elements in dual polarization mode. It can replace more complex feed arrangements containing up to three separate components. One version of the six port device is made up of a network of transmission lines connected in parallel. Another six-port device implementation is a network of transmission lines connected in series. Both versions can feed antenna elements to simultaneously transmit/receive dual orthogonal linear or circular polarizations.
