Communication system with broadband antenna

An antenna assembly comprising:

• a first antenna configured to receive a signal from a source;
• a second antenna, substantially identical to the first antenna, and configured to receive the signal;
• a waveguide feed network coupled to the first and second antennas and including a first feed port and a second feed port, the waveguide feed network being constructed to receive the signal from the first and second antennas and to provide a first component signal having a first polarization at the first feed port and a second component signal having a second, orthogonal, polarization at the second feed port;
• and
• a polarization converter unit coupled to the first feed port and the second feed port that is configured to compensate for any polarization skew between the antennas and the source.

An antenna assembly comprising:

• an antenna adapted to receive an information signal from a source;
• an orthomode transducer coupled to a feed point of the antenna and having a first port and a second port, the orthomode transducer being constructed to receive the information signal from the antenna and to split the information signal to provide, at the first port, a first component signal and, at the second port, a second component signal, the second component signal being orthogonally polarized to the first component signal;
• and
• a polarization converter unit coupled to the first and second ports of the orthomode transducer and configured to receive the first and second component signals and to compensate for polarization skew between the antenna and the source.
