Antenna system for mobile communication

摘要

An antenna for mobile communication includes a sleeve antenna having a feed point; at least one linear parasitic element insulated electrically form the sleeve antenna; and a supporting means for supporting the sleeve antenna and the linear parasitic element. The supporting means supports the sleeve antenna and the linear parasitic element so that the feed point of the sleeve antenna is located at a different elevation from an elevation of a central point of the linear parasitic element.
