Abstract
A retractable antenna is in the form of a tape (7) which is slidably mounted in a passageway (6). An electrical contact (9) for making connection to the antenna is provided on the rear wall (3) of the passageway. The tape (7) or the passageway (6) or both are shaped so as to form a bend, e.g. a bow, across the width of the tape so that (a) the convex side of the tape confronts the contact (9) and (b) rigidity is imparted to the tape to keep it upright when extended from the passageway. This antenna is slim and lightweight and therefore ideally suited for use with a compact portable radio telephone.
