Abstract

A receiver system and method for receiving signals are provided, wherein the system includes a plurality of antenna elements configured to receive a transmitted signal. A receiver device is in communication with the plurality of antenna elements, wherein the receiver device is configured to emit an output based upon the received signal, and communicate a control signal that corresponds to a determined signal quality of the received signal. A switch device is adapted to switch among the plurality of antenna elements to electrically connect a selected antenna element of the plurality of antenna elements to the receiver device. A controller is in communication with the receiver device, such that the controller receives the control signal, wherein the controller commands the switch device to directly switch to any of the antenna elements to electrically connect one of the plurality of antenna elements to the receiver device based upon the control signal.

a plurality of antenna elements configured to receive a transmitted signal;

a receiver device in communication with said plurality of antenna elements, wherein said receiver device is configured to emit an output based upon said received signal, and communicate a control signal that corresponds to a determined signal quality of said received signal;

a switch device adapted to switch among said plurality of antenna elements to electrically connect a selected antenna element of said plurality of antenna elements to said receiver device; and

a controller in communication with said receiver device, such that said controller receives said control signal, wherein said controller commands said switch device to directly switch to any of said plurality of antenna elements to electrically connect one of said plurality of antenna elements to said receiver device based upon said control signal, wherein a single electrically conductive element electrically connects said receiver device and said switch device, such that said signal received by said selected antenna element and said control signal are both communicated between said receiver device and said switch device by said single electrically conductive element.

2. The receiver system of claim 1, wherein said control signal corresponds to said determined signal quality, such that said control signal comprises a command for switching directly to another antenna element of said plurality of antenna elements in any order to said selected antenna element when said determined signal quality of said selected antenna element is below a threshold value.

3. The receiver system of claim 1, wherein said controller commands said switch device to directly switch among said plurality of antenna elements non-sequentially based upon said received control signal.

4. The receiver system of claim 1, wherein each of said plurality of antenna elements has a designated voltage potential value, such that said control signal comprises an electrical power supplied at a voltage potential so that said controller commands said switch device to switch to one of said plurality of antenna elements which has said designated voltage potential value that corresponds to said voltage potential of said control signal.
