RF tire pressure signal sensor antenna and method of packaging

摘要

A method and apparatus for communicating a signal from an external transmitter located in a remote location to a sensor mountable in an interior of a pressure vessel including a vehicle tire. The method and apparatus include disposing a pressure transducer assembly within the pressure vessel or tire in communication with a fluid. The transducer is operably connected to circuitry including a receiver circuit disposed on a PCB. A signal is transmitted from the external transmitter and received with an antenna disposed on the PCB operably connected with said receiver circuit. The antenna is configured as a trace coil disposed on at least two layers of the PCB with each of the trace coils being wound on a corresponding layer in an essentially spiral configuration. Each of the trace coils are on a corresponding layer being and serially connected to a contiguous trace coil disposed on a contiguous layer.
