Miniature antenna having a volumetric structure
First Claim
1. A miniature antenna comprising:
- a radiating element;
a conducting ground plane acting in cooperation with the radiating element;
a common feed point;
wherein the radiating element comprises;
a plurality of radiating arms extending away from the conducting ground plane; and
a top-loading portion;
wherein at least one of the plurality of radiating arms comprises a top edge connected to the top-loading portion;
wherein the top-loading portion is arranged substantially perpendicularly to the plurality of radiating arms;
wherein the common feed point is connected to the plurality of radiating arms;
wherein at least two of the plurality of radiating arms are separated by a pre-defined distance; and
wherein the physical dimensions of the radiating element are smaller than one-fifteenth of a longest free-space operating wavelength of the miniature antenna.

Abstract
A miniature antenna includes a radiating arm that defines a grid dimension curve. In one embodiment, the radiating arm includes a planar portion and at least one extruded portion. The planar portion of the radiating arm defines the grid dimension curve. The extruded portion of the radiating arm extends from the planar portion of the radiating arm to define a three-dimensional structure. In one embodiment, the miniature antenna includes a first radiating arm that defines a first grid dimension curve within a first plane and a second radiating arm that defines a second grid dimension curve within a second plane. In one embodiment, the miniature antenna includes a radiating arm that forms a non-planar structure.
