| 摘要 |
The present invention relates to a communication unit (50, 58) comprising a radio module (50, 58) and an antenna (30, 40) to be coupled thereto. The communication unit (50,58) and the antenna (30, 40) are connected together by a first pair of contacts (33, 43, 51, 55) across which an antenna signal can be transmitted. In addition, the communication unit (50,58) is equipped with a second pair of contacts (35, 52) across which ground potential can be provided by the communication unit (50, 58) to the antenna (30, 40) or to an antenna cable shield. The second pair of contacts (35, 52) are at a distance from the first pair of contacts (33, 43, 51, 55). The contacts may comprise pins, plugs, sockets or any other suitable contacts. The communication unit enables a durable and reliable antenna solution to be implemented, e.g., within a PCM/CIA data card (50, 58).
