This article presents a novel internal high-gain handset phone antenna design for STICS system application. STICS is the Satellite and Terrestrial Integrated Mobile Communication System in the 2GHz band in Japan. This article demonstrates that 1.5 wavelength folded loop radiator is a very promising antenna solution for the future STICS mobile phone terminals for satellite-link functions. The proposed antenna can be closely integrated at the top side-edge of a corner of a handset ground plane with an internal-type and low-profile antenna size (3 mm height only protruded from the side-edge). A broadside fan-shape radiation pattern toward the sky can be formed successfully by the proposed antenna in the desired 2GHz band. Besides, the radiation pattern can achieve a wide coverage with 3 dB beamwidth over 150 degree and peak antenna gain over 4.5 dBi in the vertical plane cross the handset ground plane. The constructed prototype has been studied in this paper.
