Abstract

A microwave system comprising a center fed parabolic reflector; a radio transceiver, said transceiver disposed on a circuit board and coupled to a radiator, said radiator disposed on the circuit board and extending orthogonally from a surface of the circuit board. Embodiments also include directors on the circuit board and a sub-reflector comprising a thin plate disposed on a weather proof cover and said sub-reflector having a substantially concave surface with a focus directed towards the radiator. The circuit board may be physically integrated within the feed mechanism of the center fed parabolic reflector and the radio transceiver is configured to provide OSI layer support.

Claims

1. A device comprising:

a center-fed reflector;

a radiator pin, said radiator pin radially disposed on a substrate and extending orthogonally from a first surface of the substrate;

a radio transceiver, said transceiver disposed on the substrate and coupled to the radiator pin;

one or more directors disposed on said substrate, each director disposed substantially parallel to the radiator pin;

at least one sub-reflector, said sub-reflector comprising a thin plate said sub-reflector having a first surface substantially disposed towards the radiator pin,

wherein the substrate is disposed within a feed mechanism of the center fed reflector, and the directors and the sub-reflector are disposed to re-radiate energy from the transceiver to the center-fed reflector and minimize interference to the transceiver; and

,

an antenna tube, wherein the antenna tube houses the feed mechanism.

2. The device of claim 1 wherein the radio transceiver couples to a client station via an Ethernet cable, wherein the radio receiver receives power through the Ethernet cable.

3. The device of claim 1 wherein the radio transceiver is configured to provide open system interconnection (OSI) layer support.

4. The device of claim 3, wherein the OSI layer support is provided with a gateway.

5. The device of claim 3, wherein the OSI layer support is provided by a client controller.

6. The device of claim 1 further including:

a second radiator pin, said second radiator pin disposed on the substrate and extending orthogonally from a second surface of the substrate.

7. The device of claim 6 further including:

one or more second directors disposed on said second surface of the substrate, each second director disposed substantially parallel to the second radiator pin.

8. A device comprising:

a center-fed parabolic reflector;

a first radiator pin, said first radiator pin radially disposed on a substrate and extending orthogonally from a first surface of the substrate;

a second radiator pin, said second radiator pin disposed to extend orthogonally from a second surface of the substrate;

a transceiver disposed on the first surface of the substrate and coupled to the first and second radiator pins;

one or more directors disposed on said substrate, each director disposed substantially parallel to the first radiator pin;

one or more second directors, each second director disposed substantially parallel to the second radiator pin;

at least one sub-reflector, said sub-reflector said sub-reflector having a first surface substantially disposed towards the first radiator pin,

wherein the substrate is disposed within a feed mechanism of the center fed parabolic reflector antenna, and the first and second directors and the sub-reflector are disposed to re-radiate energy from the transceiver to the center-fed reflector and minimize interference to the transceiver; and

,

an antenna tube, wherein the antenna tube houses the feed mechanism.

9. The device of claim 8 wherein the radio transceiver couples to a client station via an Ethernet cable, wherein the radio receiver receives power through the Ethernet cable.

10. The device of claim 8 wherein the radio transceiver is configured to provide open system interconnection (OSI) layer support.

11. The device of claim 10, wherein the OSI layer support is provided with a gateway.

12. The device of claim 10, wherein the OSI layer support is provided by a client controller.
