(54)METHOD AND APPARATUS


(57) An antenna is described, which has a conductive annulus arranged on the surface of a flat planar dielectric substrate. The antenna comprises first and second lands of conductive material which are also arranged on the surface of the substrate, outside the annulus. The first conductive land provides a part of a first port for exciting a first polarisation mode of the antenna. The second conductive land provides a part of a second port for exciting a second polarisation mode of the antenna, orthogonal to the first mode. The antenna may be used for multiple-input, multiple-output (MIMO) operation.
