COMMUNICATION SYSTEM WITH BROADBAND ANTENNA
First Claim
1. An communications system comprising:
- an antenna array including plurality of horn antennas configured to receive an information signal from a source, the plurality of horn antenna elements extending from a first end of the antenna array to a second end of the antenna array, each horn antenna element configured to receive an information signal and to provide at a feed point of the horn antenna element an antenna output signal;
a waveguide feed network coupled to each horn antenna of the plurality of antennas and constructed and arranged receive the information signal from the plurality of horn antennas, configured to split the information signal into a first component signal having a first polarization and a second component signal having a second polarization, the second polarization being orthogonal to the first polarization, and to provide a first summed component signal at a first feed port and a second summed component signal at a second feed port;
a converter unit coupled to the first and second feed ports and configured to receive the first summed component signal and the second summed component signal and to compensate for polarization skew between the antenna array and the source and to provide an output signal.

Abstract
A communication system including a plurality of horn antennas, a waveguide feed network, and a converter unit coupled to the plurality of horn antennas is disclosed. The waveguide feed network is coupled to each horn antenna, splits an information signal into a first component signal having a first polarization and a second component signal having a second polarization and provides a first summed component signal at a first feed port and a second summed component signal at a second feed port. The converter unit receives the first summed component signal and the second summed component signal and compensates for polarization skew between the antenna array and a source.
