US 2019/0157748 A1 · ANTENNA DEVICE

Abstract

An antenna device configured to be used at or in proximity to a user, the antenna device includes: an antenna structure having a conducting element, the conducting element extending over a length of between 1/16 of a wavelength and a full wavelength in a direction substantially orthogonal to a surface of the user, when the antenna device is provided in an intended operational position. A device includes: a housing having an operational position with respect to a user of the device; and an antenna structure coupled to the housing and having a conducting element, wherein the antenna structure is configured to emit an electromagnetic field so that the electromagnetic field propagates in a direction having a major directional vector that corresponds with a surface of a user using the device when the housing is at the operative position.

Dependent claims

An apparatus comprising:

a housing having a surface for placement against a user of the apparatus;
a circuit in the housing;
and
an antenna coupled to the circuit, the antenna having a first segment and a second segment, the first segment coupled to transmit energy between the circuit and the second segment, wherein the first segment extends along a first direction having a first major directional component that is perpendicular to the surface of the housing, and wherein the second segment extends along a second direction having a second major directional component that is parallel to the surface of the housing;
wherein the antenna is configured to emit an electromagnetic field that (1) has an electric field polarized in a direction that is at an angle with respect to a surface of the user, and (2) has at least a majority propagating in a direction along the surface of the user.
