ANTENNA SYSTEM

摘要

PROBLEM TO BE SOLVED: To form a small display part which can display information to an outer part when it is used for the radio machine of mobile communication and the like. SOLUTION: A radiation conductor element 10 and a ground plate 11 facing the element 10 are connected through a loading element 15. Thus, an antenna can be miniaturized by prolonging the effective peripheral length of the antenna. Thus, opening parts 12 are installed in the radiation conductor element 10 and the ground plate 11 and therefore a display part can be formed. It is preferable that the loading element 15 is constituted of a chip capacitor.
