Abstract:
A radio communications card holder assembly, comprising:a) a multilayer, radio frequency circuit board having a connector end for connection to a connector, an antenna end for connection to an antenna, and opposite sides extending between the ends, the board includingi) a planar, electrically conductive, ground layer having opposite planar major surfaces, andii) an analog circuit layer and a digital circuit layer respectively located at, and disposed parallel to, the opposite major surfaces, for performing radio frequency communication to and from the board via the antenna, the circuit layers having electrically conductive, side and end traces in electrical contact with, and at a common electrical potential as, the ground layer only at the sides and the antenna end of the board, respectively, the circuit layers having electrical conductors at the connector end; andb) a holder includingi) a frame of electrically conductive material, for holding the board, the frame having side rails for supporting and electrically contacting the side traces, a header rail for supporting and electrically contacting the end trace, and a cross rail extending between the side rails and parallel to the header rail, the electrical conductors extending past the cross rail, andii) a pair of covers of electrically conductive material and mounted on the frame in an overlying relationship with the analog and digital circuit layers, respectively.
