Problems solved by technology

However, due to the large amount of space required by antennas within mobile communication devices, existing mobile communication devices may need to be redesigned to provide the necessary space for additional antennas
This design is very expensive and time consuming, and the resulting design requires mobile communication devices to be larger and heavier than the average user expects

Abstract

A system that effectuates receive diversity within a mobile communication device is provided. A first antenna facilitates reception of signals in a PCS band, and a second antenna facilitates reception of signals in a GPS band and a PCS band. Tuning of the second antenna depends upon a signal type relayed to the second antenna.

Description

technical field [0001] The present invention generally relates to mobile communication devices. In particular, the present invention relates to receive diversity and GPS communication within a mobile communication device using a single antenna configuration. Background technique [0002] Early mobile communication devices used analog wireless transmissions, eg Advanced Mobile Phone System (AMPS). This analog technology is sufficient for the emerging mobile communication customer market. However, tens of thousands of new mobile subscribers require more and more air time in a relatively short period of time, and this pushes existing analog technologies to their capacity limits, or ceilings. As a result, dropped calls and busy signals have become common, accelerating the need for improved mobile communication networks. [0003] In response to this need, the industry has developed digital wireless technologies capable of delivering increased network traffic within the limited...
