Antenna for wireless communications

摘要

An apparatus includes an antenna structure with a core shaped as a toroid that is designed to be worn on a human digit. A first and second contact are located on the core. A conductive path connects the first contact and the second contact and includes a first set of windings that traverse a circumference of the core in a substantially parallel manner; and a second set of windings that traverse the circumference of the core in a substantially parallel manner. The windings are such that, from a vantage point exterior to the core, the first set of windings is substantially perpendicular to the second set of windings.

1. An apparatus comprising:
an antenna structure includes:
a core shaped as a toroid that is designed to be worn on a human digit;a first contact on the core;a second contact on the core; anda conductive path connecting the first contact and the second contact and including:
a first set of windings that traverse a circumference of the core in substantially parallel manner;a second set of windings that traverse the circumference of the core in a substantially parallel manner; andwherein, from a vantage point exterior to the core, the first set of windings, at a location on an exterior of a portion of the core, is substantially perpendicular to the second set of windings, at a location on an interior of the portion of the core.
