RF tire pressure signal sensor antenna and method of packaging

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.
