    • The present invention discloses a proactive gain control system for a communications receiver. The proactive gain control system includes a variable gain module for outputting an output signal in response to an input signal. A detector detects the output signal and outputs a detection signal representing a signal strength of the output signal. A traffic monitor monitors the output signal and outputs a traffic profile signal indicating that a traffic profile for the input signal will change. A gain computing module outputs a gain adjustment value in response to the detection signal and the traffic profile signal. A gain control module outputs a gain control signal to the variable gain module, which determines a gain between the input and output signals, in response to the gain adjustment value.

    • A system and method improves linearly-polarized microstrip patch antenna performance and fabrication through the incorporation of a pin fin ground plane and an integral antenna feed assembly. In one embodiment, a patch antenna system includes an antenna area with a patch antenna that provides radio communications. A heat dissipation member is coupled to the antenna area and includes a plurality of pins that provide for both the dissipation of heat from the antenna area and a ground plane for the antenna area. An antenna feed line is further coupled with the antenna patch for providing an electrical connection from the antenna patch to other electronic circuitries, such as a wireless device that may be mechanically coupled to the heat dissipation member. Heat generated during the operation of the wireless device is directed to ambient air by way of the heat dissipation member.
