MULTI-POLARIZED FEEDS FOR DISH ANTENNAS
First Claim
1. A multi-polarized forward feed and dish configuration for transmitting and/or receiving radio frequency (RF) signals, said configuration comprising:
- a first conductive reflector dish having a first focal point;
a second conductive reflector dish having a second focal point;
a first multi-polarized ground plane beam antenna positioned substantially at said first focal point to act as a transmit/receive feed for said first conductive reflector dish; and
a second multi-polarized ground plane beam antenna positioned substantially at said second focal point to act as a transmit/receive feed for said second conductive reflector dish.

Abstract
A multi-polarized forward feed and dish configuration for transmitting and/or receiving radio frequency (RF) signals is disclosed. The configuration comprises a conductive reflector dish, having a focal point and a vertex point, and a multi-polarized forward feed element positioned substantially at the focal point. The forward feed element comprises at least two radiative members each having a first end and a second end. The second ends of the radiative members are electrically connected at an apex point and are each disposed outwardly away from the apex point toward the vertex point at an acute angle relative to an imaginary plane intersecting the apex point.
