摘要：
A computer apparatus (40) for receiving a removable communication card (44) such as a radio card or a modem card. A radio or modem is self-contained inside a housing of the communication card (44) and has an electrical interface for communicating information to and from the computer apparatus (40). The computer apparatus (40) receives the communication card (44) such that it engages the electrical interface. A radio communication card (44) is connected to the appropriate antenna or antennas for the type and frequency of the radio. Antenna contacts are disposed on the cap to engage the antenna contacts positioned on the end of the radio card. The antenna or antennas are embedded in the cap or attached to the housing of the computer device (40).
