First Claim
Patent Images
1. An antenna system comprising:
- a conductive antenna element, at least a portion of which is described by a fractal or self-similar geometry including two or more scalings, rotations, and/or offsets of a generator motif structure; and
a housing that holds the antenna element and is adapted to be worn attached to a body appendage.

Abstract
Antennas, antenna systems, and communications devices are described that provide an antenna utilizing a fractal and/or self-similar conductive element that is novel and inventive in that its small in size and exhibits multiple-band or wideband frequency coverage which allows a miniature communications device incorporating the antenna to operate (e.g., function) with wide-band capabilities in close-proximity to a user'"'"'s body and in form factor suitable for wearing by the user. As noted above, previous size and performance limitations of prior art antennas/devices were poor and made those devices either of limited utility or inoperable.

3. A miniature radio frequency (RF) communications device comprising:
-
an antenna element at least a portion of which is described by a fractal geometry including two or more scalings, rotations, and/or offsets of a generator motif structure; a housing that holds the antenna element and is adapted to be worn attached to a body appendage; and a RF transceiver operative to synthesize, transmit, receive, and demodulate RF signals of a desired wideband frequency range; wherein the communications device is configured for wearing directly attached to or in tactile proximity to a user'"'"'s body appendage, and wherein the communications device is operative when the user'"'"'s body appendage and the RF transceiver are both in the nearfield of the device. - View Dependent Claims (4, 5, 6)
