Remote access device having multiple inductive coil antenna
First Claim
1. A remote access device comprising:
- an antenna including a first inductor having a first axis and second inductor having a second axis, wherein the first axis is non-parallel to the second axis such that the first inductor generates a first magnetic field associated with a first plane and the second inductor generates a second magnetic field associated with a second plane different than the first plane; and
a housing for the antenna.

Abstract
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.
