Abstract: Methods and apparatus are presented for a digital radio receiver using antenna to receive a signal or signals using at least one other method of diversity. In exemplary embodiments of the present invention, both switched antenna diversity and at least one other method of diversity can be utilized in a digital radio broadcast system. In exemplary embodiments of the present invention the timing of an antenna control signal in a receiver can be synchronized so that switchover to a different receiving antenna can occur between adjacent blocks of data being received from whichever of the other diversity sources is then, on average, providing the better reception. For digitally coded transmissions, a clock signal can be provided by a signal processor so as to trigger a diversity controller to switch at an optimum switching time, such as, for example, between groups or “blocks” of digitally encoded information, thus eliminating or minimizing disruption of a contiguous data stream.

Abstract: A method and system of providing an antenna for a communication system is provided that has a LNA mounted above the modular patch antenna. The resulting SDARS antenna has an ultra-low profile providing a more acceptable size for the user while maintaining the antenna gain requirements.
