1. A loaded antenna comprising:
- a radiating element comprising a first part and a second part;
the first part comprising at least one conducting surface; and
the second part comprising a loading structure, the loading structure comprising at least one conducting strip connected at at least one point on an edge of the at least one conducting surface, the maximal width of the at least one conducting strip being less than a quarter of the longest straight edge of the conducting surface; and
wherein at least a portion of the at least one conducting surface is a multilevel structure comprising a plurality of polygons, all of the plurality of polygons having at least four and the same number of sides, a plurality of the plurality of polygons being electromagnetically coupled via capacitive coupling or ohmic contact to define a plurality of contact regions and wherein, for at least 75% of the plurality of electromagnetically coupled polygons, a contact region is less than 50% of the perimeter of an electromagnetically coupled polygon.

Abstract
A novel loaded antenna is defined in the present invention. The radiating element of the loaded antenna consists of two different parts: a conducting surface and a loading structure. By means of this configuration, the antenna provides a small and multiband performance, and hence it features a similar behaviour through different frequency bands.

12. A loaded antenna comprising:
-
a radiating element comprising a first part and a second part; the first part comprising at least one conducting surface; and the second part comprising a loading structure, the loading structure comprising at least one conducting strip connected at at least one point on an edge of the at least one conducting surface, the maximal width of the at least one conducting strip being less than a quarter of the longest straight edge of the conducting surface; wherein the at least one conducting strip is shaped as a space-filling curve comprising at least ten segments connected so that no pair of adjacent segments defines a longer straight segment and, if the curve is periodic along a fixed straight direction of space, the period is defined by a non-periodic curve comprising at least ten connected segments and no pair of the adjacent and connected segments defines a straight longer segment; and wherein the space-filling curve intersects with itself at most only at its initial and final point. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A loaded antenna comprising:
-
a radiating element comprising a first part and a second part; the first part comprising at least one conducting surface; and the second part comprising a loading structure, the loading structure comprising at least one conducting strip connected at at least one point on an edge of the at least one conducting surface, the maximal width of the at least one conducting strip being less than a quarter of the longest straight edge of the conducting surface; and wherein at least a portion of the at least one conducting surface is a multilevel structure comprising a plurality of polygons, all of the plurality of polygons having at least four and the same number of sides, the plurality of polygons being generally identifiable by the free perimeter thereof as a geometrical element and wherein projection of the exposed perimeters of the plurality of polygons defines the least number of polygons necessary to form a generally distinguishable element where polygon perimeters are interconnected, a plurality of the plurality of polygons being electromagnetically coupled via capacitive coupling or ohmic contact to define a plurality of contact regions and wherein, for at least 75% of the plurality of electromagnetically coupled polygons, a contact region is less than 50% of the perimeter of an electromagnetically coupled polygon.
