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.
Claims22
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 and a mounting mechanism for mounting of said feed element at a position 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.
A multi-polarized forward feed for transmitting and/or receiving radio frequency (RF) signals to/from a reflector dish, said forward feed comprising:
- 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 at an acute angle relative to an imaginary plane intersecting said apex point;
- and
- a truncated pyramidal conductor that includes a closed truncated side, an open base side, and three closed trapezoidal sides, and wherein an open interior space of said truncated pyramidal conductor encompasses said radiative members such that said apex point is approximately at a center point of said closed truncated side and said radiative members are disposed outwardly away from said closed truncated side toward said open base side.
