Abstract

A fixed antenna (129) and wireless communication device operable in at least two frequency bands. The fixed antenna (129) has a dual band radiating element (310) with a first radiating element portion (320) and a second radiating element portion (330) having a different length than that of the first radiating element portion (320). There is also a tuning stub (340) having an axial length parallel with a central longitudinal axis (A) of the dual band radiating element (310), this axial length does not exceed one sixth of a total effective length of the dual band radiating element (310). A feed point (350) is electrically coupled to the tuning stub (340) and the dual band radiating element (310). In use, the first radiating element portion (320) provides for tuning into a first frequency and the second radiating element portion (330) provides for tuning into a second frequency.
