Abstract

A retractable stubby antenna is movable relative to a housing along a longitudinal axis. In a retracted position, at least a portion of the retractable stubby antenna is positioned within the housing. In an extended position at least a portion of the retractable stubby antenna is positioned outside of the housing such that a greater portion of the antenna is positioned outside the housing in the extended positioned than in the retracted position. A radiating helical element is connected to device circuitry through a connection interface including an antenna interface and a housing connection interface.

Claims

1. A retractable stubby antenna device comprising:

a housing comprising a housing connection interface;

a retractable stubby antenna moveable relative to the housing along a longitudinal axis of the retractable stubby antenna and comprising;

a flex circuit having a flex circuit conductor forming a helical radiating element;

a conductive tube connected to the helical radiating element and configured to slideably receive the housing connection interface to form an electrical connection between the housing connection interface and the flex circuit at least when the retractable stubby antenna is in a retracted position where at least a portion of the retractable stubby antenna is within the housing and when in the retractable stubby antenna is in an extended position where a greater portion of the retractable stubby antenna is outside the housing than when in the retracted position.

2. A retractable stubby antenna device in accordance with claim 1, further comprising a core, the flex circuit applied to an outer surface of the core.

3. A retractable stubby antenna device in accordance with claim 2, wherein the conductive tube is positioned within a channel of the core extending along the longitudinal axis of the antenna.

4. A retractable stubby antenna device in accordance with claim 1, wherein the housing interface connection comprises a ball contact slideably positioned within the conductive tube.

5. A portable communication device comprising:

a housing comprising a housing connection interface;

device circuitry situated within the housing;

a retractable stubby antenna moveable relative to the housing along a longitudinal axis of the retractable stubby antenna and comprising;

a flex circuit having a flex circuit conductor forming a helical radiating element;

a conductive tube connected to the helical radiating element and configured to slideably receive the housing connection interface to form an electrical connection between the housing connection interface and the flex circuit at least when the retractable stubby antenna is in a retracted position where at least a portion of the retractable stubby antenna is within the housing and when in the retractable stubby antenna is in an extended position where a greater portion of the retractable stubby antenna is outside the housing than when in the retracted position.
