A combination antenna has two antenna parts (8; 9, 9a, 17) and a connector part (10) to connect them to a radio apparatus. The first antenna part is a whip antenna and the second antenna part comprises a planar surface and a conductive pattern (16) formed on it to transmit and receive radio-frequency radiation. When the antenna parts are mechanically coupled to the connector part the plane surface, which includes a radiating conductive pattern, is separated from said first antenna part. In addition, the second antenna part or another part of the construction may include a plane surface with a plating on it, which in the normal operating position protects the user's head from radiation.
