On-board signal transmitter for implementing keyless procedure

摘要

A signal transmitter (11) communicates with a portable receiver (12) for implementing a keyless entry procedure. A loop antenna is connected to the signal transmitter by two wire conductors (1, 2) which are twisted together along a portion of their length (22) down to a branching point (B2) where the two wire conductors separate from one another in order to form at least a portion of said loop antenna. <IMAGE>
