Orthogonal mode junction (OMJ) for use in antenna system

An orthogonal mode junction for use in a multibeam antenna system, the junction comprising:

• a housing;
• a feed area for simultaneously receiving first signals of a first polarity and second signals of a second polarity which is orthgonal to the first polarity;
• isolating means within said housing for isolating said first signals from said second signals;
• a first channel through which the first signals of the first polarity travel toward and into a first waveguide;
• a second channel through which the second signals of the second polarity travel toward and into a second waveguide;
• wherein said isolating means causes said first signals of said first polarity to be forwarded into the first channel and the second signals of the second polarity to be forwarded into the second channel;
• and
• wherein first and second dielectric lenses are disposed within first and second parallel plate waveguides that are attached to the first and second channels, respectively, of the junction.
