Modeling and design of 2-element dual-band ceramic chip handset antennas
This paper presents the modeling and design of 2-element compact ceramic chip antenna for UMTS/GPS dual-band mobile handset applications. First, the design of ceramic chip monopole integrated with a simple matching circuit will be explained. The radiation characteristics including high gain and total efficiency of the proposed compact antenna element will be presented. Next, 2-element antenna system for dual-band handset design where one antenna element is used for UMTS operation while the another one works as an assisted GPS (A-GPS) antenna will be introduced. Parametric study illustrating the effect of antenna elements separation on the mutual coupling between antenna ports will be analyzed. It has been shown that low mutual coupling is the result of strong current being induced on the 3D monopole placed inside high density dielectric ceramic pad. Mobile handset applications of the proposed compact 2-element antenna system will be discussed in the details at the Conference.
