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.
