Radio card having independent antenna interface supporting antenna diversity
First Claim
1. A radio card used in an electronic device having a device housing, a track for engagingly receiving the radio card, a first interface and a first antenna, the radio card comprising:
- a card housing;
a second interface, disposed on the card housing, that, upon receipt of the radio card by the electronic device, engagingly couples with the first interface;
a radio circuit, disposed within the card housing, communicatively coupled to the second interface;
a third interface, electrically and physically independent of the second interface, disposed on the card housing; and
the third interface being communicatively coupled to the radio circuit, and the third interface engagingly coupling with the first antenna upon receipt of the radio card by the electronic device via the track.

Abstract
A radio card, such as a PCMCIA card, received by an electronic device has a first interface coupling radio circuitry within the radio card to the electronic device. The radio card also has a second interface, independent of the first interface, that couples with an antenna disposed within the electronic device upon receipt of the radio card by the electronic device. The second interface may comprise a plurality of antenna contacts located along tracks of the electronic device used to aid reception of the radio card. A second and possibly external antenna may also automatically couple with the second interface upon insertion. By selective placement of the antenna contacts on the radio card, a specific one of the antennas may be selected. Otherwise, internal switching circuitry supports antenna diversity or simultaneous use of a plurality of antennas.
