Abstract
Official abstract text for this publication.
An apparatus includes an internal, multiband antenna element concealed within a portable communication device. The antenna element operates in at least three frequency bands and includes geometric elements arranged to define empty spaces in the antenna element to provide at least three winding current paths through the antenna element which circumvent the empty spaces, the at least three winding current paths respectively corresponding to the at least three frequency bands to provide the antenna element with multi-band behavior, wherein each of two or more of the geometric elements is traversed by the at least three winding current paths. The apparatus further includes a ground plane, with the antenna element being electrically coupled to the ground plane. The geometric elements are arranged such that the antenna element does not comprise a group of single band antennas that respectively operate in the at least three frequency bands.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: an internal antenna element having a multi-band behavior, the antenna element being concealed within a portable communication device and configured to operate in at least three frequency bands, the antenna element comprising a plurality of geometric elements arranged to define empty spaces in the antenna element to provide at least three winding current paths through the antenna element which circumvent the empty spaces, the at least…
