1. An antenna element comprising:
- a film of dielectric material having thereon a radiating antenna element that radiates at a fixed, first order harmonic frequency within a desired first frequency band, the radiating antenna element radiating at a second order harmonic frequency, the film of dielectric material having thereon a conducting capacitive load element on the same side of the film as the radiating antenna element, the capacitive load element and the radiating antenna element being capacitively coupled across a thickness of the film at the second order harmonic frequency, with the film being rolled into a sleeve shape, to tune the radiating antenna element to the radiated second order harmonic frequency to correspond with a desired second frequency band, thereby providing a dual band antenna element.

Abstract
An antenna element (1) includes, a film (10) of dielectric material having thereon a radiating antenna element (14) that radiates at a first order harmonic frequency within a desired first frequency band, a conducting capacitive load element (90) and the radiating antenna element (14) being capacitively coupled across a thickness of the film (10) at a second order harmonic frequency, to tune a radiated second order harmonic frequency to correspond with a desired second frequency band, thereby providing a dual band antenna element (1).
