Abstract
An antenna for receiving signals from GPS and GSM comprises a cylindrical body formed of dielectric material, an axial central through hole, a first conductor layer coated on the bore of the through hole, a ground conductor layer coated on the bottom of the body being in contact with the first conductor layer, an insulator fitted into the through hole, a feeding pin provided in the center of the insulator with both ends extended above the top and the bottom of the body wherein the end atop the body being attached to a helical antenna, and a patch antenna formed on the circumferential surface of the body such that the antenna can receive signals from GPS and GSM respectively. This greatly reduces the size of antenna as well as reduces the manufacturing and transporting costs.
