description An antenna apparatus 12 comprises a feed point (FP); and a radiator 20 integrated with a glazing arrangement 30, where the radiator 20 includes a branch 204 or 206 which is resonant in a first frequency band. The apparatus may include transceiver or transmitter circuitry which is connected to the feed point and a ground plane which is not integrated with the glazing arrangement 30. The radiator 20 may be a flexible printed planar patch arrangement for being adhesively secured to a curved surface of glazing 30 and operating with a first frequency band which may be at least 0.6 GHz. Alternatively, the radiator 20 may be laminated within the glazing 30. A symmetrical radiator 20 conductive pattern with a slot separating and inner pattern from an outer pattern may be used. The glazing may include an infra-red reflective layer with a gap in the layer at the location of the radiator 20. A conductive panel of a vehicle may be used as the ground plane.
