发明名称 System and method for remote convenience function control utilizing near isotropic receiving antenna system
摘要 A remote convenience system (10) and an associated method provide for remote control a convenience function. A portable transmitter unit (12) is operable for remote function requests. The transmitter unit (12) includes circuitry (32) for transmitting a signal (18) that conveys a remote function request. A receiver/controller unit (14) receives the transmitted signal (18) and causes performance of the remotely requested function. The receiver/controller unit (14) includes a plurality of antennae (52), each for picking-up the transmitted signal (18) and outputting an electrical signal that conveys the remote function request. Each of the antennae (52) is configured to have an ability to pick-up the transmitted signal (18) that is dependent upon direction from the receiver/controller unit (14) to the transmitter unit (12). The ability of each of the antennae (52) is different from the ability of the other antennae. A control portion (48) determines which one of the antennae (52) has a better ability to pick-up the transmitted signal. The electrical signal from the one antenna with the better ability is used to determine the remotely requested function.
