ABSTRACT:
A retractable antenna for a wireless communicator includes an elongate radiator that slides through a helical radiator. An electrical contact alternately contacts one of the elongate radiator and the helical radiator depending on a position of the elongate radiator relative to the helical radiator. Mechanical disengagement is accomplished by the movement of the elongate radiator into a contact position with the electrical contact to disengage the helical conductor. A preferred feature of the antenna is that one of the helical radiator and elongate radiator make electrical contact with the wireless communicator circuits, even when the antenna is placed between a fully refracted and fully extended position. Multiple band operation is another feature of the retractable antenna due to its periodic nature. Ease of assembly is achieved through preferred individual snap fit components.
