Dual antenna arrangement for portable transceiver
First Claim
1. An antenna arrangement for a portable transceiver, comprising:
- (a) a printed circuit monopole antenna mounted on said transceiver and coupled to be driven by circuitry of said transceiver;
(b) an extendable monopole antenna mounted on said transceiver adapted to be electrically coupled to said printed circuit monopole antenna when in an extended position and to be electrically decoupled from said printed circuit monopole antenna when in a retracted position; and
(c) a connector having a first end fixedly attached to said printed circuit monopole antenna and a second end which maintains contact with said extended monopole antenna as it slides between said extended and retracted positions.

Abstract
An antenna arrangement for a portable transceiver is disclosed as including a printed circuit antenna mounted on the transceiver and coupled to be driven by circuitry of the transceiver. An extendable monopole antenna is also mounted on the transceiver and is adapted to be electrically coupled to the printed circuit antenna when in an extended position and to be electrically decoupled from the printed circuit antenna when in a retracted position. A connector is fixedly attached to the printed circuit antenna at a first end and maintains contact with the monopole antenna at a second end as the monopole antenna slides between the extended and retracted positions. The monopole antenna includes a conductive portion which is in contact with the connector in the extended position and a non-conductive portion which is in contact with the connector in the retracted position. A separate circuit may be provided for sensing the position of the monopole antenna, where the circuit permits the transceiver to transmit at full power when the monopole antenna is in the extended position and permits the transceiver to transmit at reduced power when the monopole antenna is in the retracted position.

25. A portable radio transceiver, comprising:
-
(a) transmitting and receiving circuitry; (b) a housing enclosing said transmitting and receiving circuitry; and (c) an antenna arrangement comprising; (1) a printed circuit monopole antenna mounted on said transceiver housing coupled to and driven by said transmitting and receiving circuitry; (2) an extendable monopole antenna mounted on said transceiver housing so as to be slidable from an extended position to a retracted position; and (3) a connector having a first end fixedly attached to said printed circuit monopole antenna and a second end which maintains contact with said extendable monopole antenna as it slides between said extended and retracted positions; wherein said printed circuit monopole antenna and said extendable monopole antenna are electrically coupled in said extended position so that said extendable monopole antenna is a radiating element of said radio transceiver and said printed circuit monopole antenna and said extendable monopole antenna are electrically decoupled in said retracted position so that said printed circuit monopole antenna is a radiating element of said radio transceiver.
