Abstract
A relatively low cost, easy to install and aesthetically pleasing digital video broadcast from satellite (DVBS) elliptical horn antenna designed to receive satellite television broadcast signals with circular polarity. This type antenna may be implemented as a multi-beam, multi-band antenna with closely spaced antenna feed horns operable for simultaneously receiving signals from multiple satellites that are closely spaced from the perspective of the antenna.
Claims16
An antenna configured to simultaneously receive signals from multiple satellites that are closely spaced from the perspective of the antenna;
- comprising:
- at least three closely spaced antenna feed horns arranged in a substantially linear array along a linear axis;
- a substantially elliptical reflector defining a major axis for feeding signals to the closely spaced antenna feed horns;
- a first feed horn of the array having an exterior contour that defines a first indentation;
- a second feed horn of the array having an exterior contour that defines a portion received within the first indentation of the first feed horn;
- and
- wherein the linear axis of the array is substantially aligned with the major axis of the reflector.
An antenna configured to simultaneously receive signals from multiple satellites that are closely spaced from the perspective of the antenna;
- comprising:
- a common housing containing at least three closely spaced antenna feed horns arranged in a linear array along a linear axis, a low noise block down converter, and a circular polarizer;
- a substantially elliptical reflector defining a major axis for feeding signals to the closely spaced antenna feed horns;
- a first feed horn of the array having an exterior contour that defines a first indentation;
- and
- a second feed of the array horn having an exterior contour that defines a portion received within the first indentation of the first feed horn;
- and
- wherein the linear axis of the array is substantially aligned with the major axis of the reflector.
