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 conductive reflector dish having a focal point and a vertex point; and
a multi-polarized forward feed element positioned substantially at said focal point, and wherein said feed element comprises at least two radiative members each having a first end and a second end, and wherein said second ends of said radiative members are electrically connected at an apex point and are each disposed outwardly away from said apex point toward said vertex point at an acute angle relative to an imaginary plane intersecting said apex point.

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.
