An antenna indexing and retaining mechanism (,) for coupling an antenna stem (,) to a transceiver (,) is provided. The mechanism (,) includes a plurality of plates disposed in a first plane (,) substantially perpendicular to an axis (,) of the antenna stem (,), a first plate (,) of the plurality of plates to engage a first antenna stem surface (,) of the antenna stem and a second plate (,) of the plurality of plates to engage a second antenna stem surface (,) of the antenna stem. The mechanism (,) also includes a release plate (,) having projections (,) extending into the first plane (,), the projections (,) causing the plurality of plates to be disengaged from the antenna stem (,) upon translation of the release plate (,).

Antenna indexing and retaining mechanism

A unique dual beam contact (30) for coupling elements on opposite sides of a dividing element (68) preferably comprises a single piece of metal or other conductive material to provide a contact portion on either side of the dividing element (14). Each beam of the dual beam contact can be specifically shaped or formed to provide the preferred contact pressure depending upon the application the dual beam contact. The dual beam contact includes an attachment member (34, 35) to provide easy attachment to an element of the device. Alternatively, the elbow portion (38) between the two beams could be used to attach the dual beam contact to the dividing element. The dual beam contact of the present invention reduces cost, inventory requirements, and complexity in manufacturing.

Dual beam contact

An electronic device employs a method and apparatus for shielding an electrical circuit (101) that is disposed on a substrate (120). A base member (103) that includes a top portion (104) and a plurality of side portions (105) is electrically coupled to a receptacle area (121) of the substrate (120) such that the plurality of side portions (105) substantially encircle the electrical circuit (101). The top portion (104) of the base member (103) includes a plurality of tab members (108) interposed with a plurality of receptacle openings (109). A substantially planar cover (102) that includes a plurality of protrusions (111) is positioned adjacent to the top portion (104) of the base member (103) such that each protrusion (111) is positioned within a corresponding receptacle opening (109). The cover (102) is then urged until each protrusion (111) interlocks with a corresponding tab member (108) to substantially enclose and, thus, shield the electrical circuit (101).
