Multilevel antennae
DCFirst Claim
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 three winding current paths respectively corresponding to the at least three frequency bands to provide the antenna element with the multi-band behavior, wherein each of two or more of the geometric elements is traversed by the at least three winding current paths; and
a ground plane, the antenna element being electrically coupled to the ground plane;
wherein 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.

Abstract
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.

32. 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 provide at least three winding current paths that circumvent empty spaces in the antenna element, the at least three winding current paths respectively corresponding to the at least three frequency bands to provide the antenna element with the multi-band behavior, wherein portions of the at least three winding current paths extend along a plurality of common geometric elements; and a ground plane, the antenna element being electrically coupled to the ground plane; wherein the geometric elements are arranged such that the antenna element does not comprise substantially non-overlapping portions that serve as respective single band antennas. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62)
