PROBLEM TO BE SOLVED: To easily enable the impedance matching to flexibly cope with the design change, etc. of an appliance. SOLUTION: The antenna element with an antenna pattern formed on a base board has a matching element mounted on the board for matching the impedance of the antenna pattern. In manufacturing the antenna element, the antenna pattern is designed, based on theoretical expressions, and the impedance of the entire antenna element including the matching element is simulated by a computer. The antenna pattern and a land for the matching element designed in a design process are formed at once in a printed circuit forming process to mount the matching element. The characteristics of the matching element are involved to make the impedance matching. COPYRIGHT: (C)2005,JPO&NCIPI
