Summary:A retractable antenna ( 100 ) is provided that includes a body ( 106 ) having an orifice ( 204 ), a whip ( 104 ) retractably coupled to the body ( 106 ), at least one follower ( 200 ) disposed about the whip ( 104 ), and a cam ( 202 ) disposed about the orifice ( 204 ). The cam ( 202 ) is shaped such that the at least one follower ( 200 ) interacts with the cam ( 202 ) during retraction of the whip ( 104 ) so as to rotate the whip as necessary to align the whip in a rotational position that allows full retraction of the antenna. Also provided are an electronic communication device ( 102 ) that includes at least one such non-circular retractable antenna ( 100 ), and an alignment system for rotationally aligning an extendable portion of a non-circular retractable antenna (100 ) during retraction.
