Antenna for receiving and/or transmitting polarized communication signals
First Claim
1. An antenna for communicating with a remote communication system, comprising:
- main and sub reflectors;
a beam shaping element facing said sub reflector and having a plurality of feeding points;
a plurality of ortho-mode transducers (OMTs); and
a plurality of waveguides each having a proximal end connected to another of said plurality of OMTs and a distal end connected to one of said plurality of feeding points;
wherein said beam shaping element is sized and shaped to form an ellipsoidal beam creating a first elliptical spot on said sub reflector by combining a plurality of polarized intermediate transmission signals;
each of said polarized intermediate transmission signals is originated from another of said plurality of OMTs.

Abstract
An antenna for communicating with a remote communication system. The antenna comprises main and sub reflectors, a beam shaping element facing the sub reflector and having a plurality of feeding points, a plurality of ortho-mode transducers (OMTs), and a plurality of waveguides each having a proximal end connected to another of the plurality of OMTs and a distal end connected to one of the plurality of feeding points. The beam shaping element is sized and shaped to form an ellipsoidal beam creating a first elliptical spot on the sub reflector by combining a plurality of polarized intermediate transmission signals; each of the polarized intermediate transmission signals is originated from another of the plurality of OMTs.

21. A method of transmitting a signal to a remote communication system as an ellipsoidal beam, comprising:
-
splitting a transmission energy to a plurality of transmission signals; separately polarizing each of said plurality of transmission signals; separately conducting each of said plurality of polarized transmission signals in one of a plurality of waveguides; combining said plurality of polarized transmission signals so as to generate an ellipsoidal beam; and directing said ellipsoidal beam as an ellipsoidal antenna beam toward the remote communication system. - View Dependent Claims (22, 23, 24, 25, 26, 27)
