摘要
Retractable antennas with quarter wave-quarter wave resonances for telephones, and which are particularly suitable for radiotelephones, include a retractable antenna with a top load element, a spatially separated rod element, and a cylindrical support conductor positioned therebetween. The cylindrical support conductor is structurally configured to receive a portion of the rod therein to add structural rigidity to the antenna and to define a coaxial capacitor between the rod and the conductor when the antenna is in the extended position.
