Filed:

Jun 14, 1999

Appl. No.:

9/333117

Inventors:

Errol Dudas - San Jose CA
Thomas J. Hutton - Cupertino CA
Norman H. Nelson - Sunnyvale CA
Patrick J. Wallace - San Jose CA

Assignee:

Symbol Technologies, Inc. - Holtsville NY

International Classification:

H05K 714

US Classification:

361800

Abstract:

This invention is directed to a PCMCIA Type II memory card holder assembly for a spread spectrum radio communication card that provides radio frequency interference shielding, electrostatic discharge resistance and heat dissipation. The card holder assembly consists of a multilayer circuit board and a card holder. The multilayer circuit board has a ground plane disposed between a plurality of analog circuit layers and a plurality of digital circuit layers. The ground plane is connected by through vias to ground traces on the surfaces of the circuit board. The card holder consists of a card holder frame in which the memory card is slidably and rotatably mounted so that the ground traces continuously contact the frame, and two outer cover plates which are adhered to the opposing surfaces of the card holder frame.

International Classification:

H01Q 124

US Classification:

343702

Abstract:

This invention is directed to a memory card assembly having a first end connected to a host device and a second end connected to a retractable antenna assembly. The memory card assembly includes a radio for two way communications between the host device and a remote location. The antenna assembly comprises a housing for two antennas and two light emitting diodes (LEDs) that indicate the status of the radio. The two antennas and the two LEDs are connected to the memory card circuit board through two dual function connectors that concurrently pass analog and digital signals.
