ABSTRACT:
An antenna assembly comprises an elongate radiating element (11) movable between a retracted position and an extended position, and a substantially planar radiating element (12) extending transversely to the elongate element. The elongate element extends through an aperture (25) in the planar element. A pair of concentric conductors (9,10) provide coaxial feed to the radiating elements and the elongate element is slidably mounted within the inner conductor (9). In the retracted position the elongate element forms part of the coaxial feed to the planar element and is itself rendered inoperative as a radiator. The invention provides a compact and convenient dual antenna arrangement ideally suited for use in a portable cellular radio telephone.
