RF tire pressure signal sensor antenna and method of packaging
First Claim
1. A pressure transducer assembly mountable in an interior of a tire for sensing a pressure of a fluid in said tire comprising:
- a sensor housing having a first compartment in fluid communication with said fluid;
a PCB slideably engaged with and removable from said sensor housing, said PCB separating a second compartment from said first compartment;
circuitry including a transceiver circuit disposed on said PCB and operably coupled to said pressure transducer;
a pressure transducer operably connected to said circuitry, said pressure transducer in fluid communication with said first compartment;
a coil antenna operably connected to said transceiver circuit, said antenna configured to receive a signal from a remote location, said antenna being a trace coil disposed on at least two layers of said multilayered printed circuit board with each said trace coil wound on a corresponding layer in an essentially spiral configuration, each said trace coil on said corresponding layer being serially connected to a contiguous trace coil disposed on a contiguous layer;
a removable power source coupled to said circuitry contained within said second compartment; and
a cover sealably engaged with said housing and said PCB such that said second compartment is not in fluid communication with said first compartment.

Abstract
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.
