Patent ID: 8098204

Claim:
A mobile communication terminal, comprising: a casing made of an electrically nonconductive material and comprising an outer cover and an inner cover, the casing having housed therein a circuit board on which a radio power supply circuit and a ground plane have been formed; an antenna element made of an electrically conductive material pattern, the antenna element being printed and formed on a face of the casing; and a connecting element electrically connecting the antenna element and the circuit board to each other, wherein the antenna element is made by printing and forming a main body of the antenna element on the face of the casing, leading a first end of the antenna element into the casing through a gap between the outer cover and the inner cover of the casing, and printing and forming the first end of the antenna element on a back face of the casing, and wherein the first end of the antenna element led into the casing is used as a tuning section for tuning one of a resonance frequency and matched impedance of the antenna element.
