Abstract: An antenna comprises first and second conducting elements and first, second and third conducting lines. Each conducting element has a conductive surface. The first conducting line provides a short circuit between the conductive surfaces. The second conducting line has a first end electrically connected to one conductive surface and a second, free end. The third conducting line has a first end electrically connected to the other conductive surface and a second, free end. The second and third conducting lines are aligned along an axis X-X and each of the second ends of the second and third conducting lines serves as one of the terminals of a two terminal port F for feeding an RF signal of wavelength λ to the antenna. The first and second conducting elements are arranged with the conductive surfaces a face-to-face relationship, spaced apart by a distance d and the first, second and third conducting lines are arranged such that, when an RF signal is fed to the antenna, currents caused to flow in one conductive surface generate a magnetic field that at least partially cancels out the magnetic field generated by currents caused to flow in the other conductive surface and currents are caused to flow in the first, second and third conducting lines.
