Abstract

A microwave system and method 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 method of radiating radio frequency energy comprising:

coupling a radio frequency (RF) transceiver to a digital network, said transceiver disposed in the feed arm of a center-fed parabolic reflector;

providing, via the digital network, a baseband signal information to the transceiver;

converting the baseband signal information into an RF signal in the microwave spectra;

transmitting the RF signal to one or more antenna feed pins,

wherein the antenna feed pins are disposed in the feed arm of the center-fed parabolic reflector on a first side of a printed circuit board,

wherein the antenna feed pins are mounted perpendicular to the printed circuit board, said feed pins disposed on the printed circuit board at a location determined to maximize radiation gain;

radiating the RF signal from the antenna feed pins such that the radiated RF signal is planar to the printed circuit board thereby minimizing induced interference to the printed circuit board; and

,

reflecting at least a portion of the transmitted RF signal to the parabolic reflector, said reflecting effectuated with directors pins, said director pins disposed on the printed circuit board.

2. The method of claim 1 wherein the baseband signal information is provided over Ethernet.

3. The method of claim 1 wherein the radio transceiver couples to a passive adapter through the digital cable, wherein the passive adapter sources power into the transceiver.

4. The method of claim 1 wherein the radio transceiver includes a radio gateway supporting OSI layers 1 to 7.

5. The method of claim 1 wherein the radio transceiver includes a client controller, supporting OSI layers 1 to 3.

6. A method of antenna transmission comprising:

providing a center-fed parabolic reflector;

providing a radio frequency (RF) transceiver, said transceiver operable to couple to a network, said network providing digital signal information;

radiating the digital signal information from the network with the RF transceiver, said radiation effected by encoding a microwave RF signal with the digital signal information;

and,

reflecting at least a portion of the radiated digital signal information to the parabolic reflector,

wherein the transceiver is disposed on a circuit board, said circuit board disposed in a feed arm of the center-fed parabolic reflector, wherein the transceiver includes one or more antenna feed pins and director pins, wherein the antenna feed pins, and director pins are mounted perpendicular to the circuit board, said feed pins and director pins shaped and positioned to maximize antenna gain;

wherein radiation of the microwave RF signal occurs planar to the circuit board such that the microwave RF signal is planar to the circuit board thereby minimizing induced interference to the circuit board.

7. The method of claim 6 wherein the radio transceiver includes a radio gateway supporting OSI layers 1 to 7.

8. The method of claim 6 wherein the radio transceiver includes a client controller, supporting OSI layers 1 to 3.
