摘要： A remote access device which may comprise an antenna having a first inductor with a first axis, a second inductor with a second axis, and a third inductor with a third axis, where the first, second and third axes may be oriented substantially perpendicular to each other, respectively, such that the first inductor generates a first magnetic field associated with a first plane, the second inductor generates a second magnetic field associated with a second plane different than the first plane, and the third inductor generates a third magnetic field associated with a third plane different than the first and second planes. The remote access device preferably includes a single form for the first, second and third inductors, where the first, second and third inductors are each wound on the form.

摘要： A transmitter circuit includes an oscillator circuit and an amplifier circuit. The oscillator circuit includes a surface acoustic wave (SAW) resonator and generates a carrier signal. The amplifier circuit receives the carrier signal and a data signal, and generates an output signal as the carrier signal modulated with the data signal.
