ABSTRACT:
A mobile radio antenna configuration scheme. A first embodiment discloses an extendable first antenna for a mobile radio that can serve as an alternative to, or in conjunction with, an internal second antenna. When in the stored position, the first antenna is disposed within the mobile radio casing so that the form factor advantages of using internal antennas are obtained. When fully extended, the majority of the first antenna is external to the mobile phone. In another embodiment, the mobile radio transceiver engine is switched from the second antenna to the first antenna upon extension of the first antenna. In another embodiment, the transceiver is connected to both antennas. In another embodiment, the antenna with the strongest signal is connected to the transceiver when the extendable antenna is extended. In another embodiment, an antenna module inserts into a mobile radio. The antenna module may have various antenna combinations for custom configuration of the mobile radio.
