Abstract

An antenna for transmitting and receiving a radio frequency signal comprises a planar radiator (801, 901), a ground plane substantially parallel to the radiator, and a feed point (402, 602, 1106). Further it comprises a separate connector part (404, 604, 1105) for forming an electrical connection between the radiator and the feed point, and means (408, 1101, 1201, 1202) for the mechanical support of the edges of the planar radiator.
