A dual band antenna for a mobile communication system which includes: a metal tube having an open end; a coaxial feed line having inner and outer conductors, with one portion of the coaxial line inserted into the metal tube, a ground plane connected to a portion of the metal tube opposite the open end and to the outer conductor of the coaxial feed line, and, a signal line electrically coupled to the inner conductor and protruding from the metal tube at the open end thereof. Preferably, the dimensions of the metal tube, the coaxial feed line and the signal line are selected such that the antenna is impedance matched to the coaxial feed line over the dual operating band, thereby obviating the need for a separate matching network.
