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;

an antenna tube disposed along the central axis of the center-fed reflector, said antenna tube including a circuit board, said circuit board having a top surface and a bottom surface;

a first radiator pin disposed on the top surface of the circuit board, and substantially perpendicular to the top surface of the circuit board;

a second radiator pin disposed on the bottom surface of the circuit board and substantially perpendicular to the bottom surface of the circuit board;

said first and second radiator pins, electrically coupled to form a half-wavelength dipole antenna;

a pair of director pins disposed through the circuit board, substantially parallel to the first or second radiator pin;

a pair of substantially similar sub-reflectors disposed on the antenna tube, each of said sub-reflectors having a first concave surface substantially disposed towards the radiator pin, and

a radio transceiver disposed on the top surface of circuit board, said radio receiver electrically coupled to the first and second radiator.

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 sub-reflector disposed on the antenna tube.
