Abstract: A tire pressure monitoring system is configured to communicate with a tire pressure sensor and has an antenna assembly and a transmitter. The antenna assembly has a transmitting and a cancelling antenna. The transmitting antenna has a wire loop defined by a plurality of coils with a first terminal and a second terminal. The cancelling antenna has a wire loop defined by a plurality of coils with a first terminal and a second terminal. The arrangement of the transmitting antenna and the cancelling antenna defines a proximal zone wherein a field from the transmitting antenna is configured to be sufficient to actuate the tire pressure monitor, while beyond the proximal zone, a field from the cancelling antenna cancels the field from the transmitting antenna. The transmitter is coupled to the transmitting antenna, and the cancelling antenna. An antenna and methods are likewise disclosed.
