1. A wireless device comprising:
- a radiating element, the radiating element comprising;
a conducting body including a hole;
an input terminal;
a ground plane, the ground plane operating in cooperation with the radiating element;
a dielectric support, wherein the radiating element is arranged on the dielectric support;
a feeding means, the feeding means being coupled to the input terminal;
wherein the radiating element defines an external perimeter;
wherein the hole has an area of at least 20% of an area included inside the external perimeter;
wherein the external perimeter of the radiating element is shaped as a first polygonal shape comprising at least four sides;
wherein a perimeter of the hole is shaped as a second polygonal shape comprising a plurality of sides;
wherein the first polygonal shape and the second polygonal shape are not similar;
wherein the radiating element is shorter than a quarter of a longest operating wavelength of the wireless device; and
wherein the wireless device is operative at multiple frequency bands.

Abstract
A new type of multihole antenna which is mainly suitable for mobile communications or in general to any other application where the integration of telecom systems or applications in a single antenna is important. The antenna includes a radiating element which at least includes one hole. By means of this configuration, the antenna provides a broadband and multiband performance, and hence it features a similar behaviour through different frequency bands. Also, the antenna features a smaller size with respect to other prior art antennas operating at the same frequency.
