COMMUNICATION SYSTEM WITH BROADBAND ANTENNA
First Claim
1. An antenna array comprising:
- a plurality of horn antenna elements arranged in at least one row 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 of the plurality of horn antenna elements configured to receive an information signal and to provide the information signal at a feed point of the horn antenna element; and
a waveguide feed network coupling the plurality of horn antenna elements to a common array feed point, the waveguide feed network configured to sum the information signals from the plurality of horn antenna elements to provide a summed signal at the common array feed point;
wherein a center-to-center horn spacing between adjacent ones of the plurality of antenna elements in the at least one row is approximately equal to one wavelength at substantially a highest transmit frequency of the antenna array; and
wherein each row of horn antenna elements comprises 32 horn antenna elements.

Abstract
A communications system including an antenna array and electronics assembly that may be mounted on and in a vehicle. The communication system may generally comprise an external subassembly that is mounted on an exterior surface of the vehicle, and an internal subassembly that is located within the vehicle, the external and internal subassemblies being communicatively coupled to one another. The external subassembly may comprise the antenna array as well as mounting equipment and steering actuators to move the antenna array in azimuth, elevation and polarization (for example, to track a satellite or other signal source). The internal subassembly may comprise most of the electronics associated with the communication system.
