Patent ID: 6958684

Claim:
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.
