<p>PROBLEM TO BE SOLVED: To provide a mobile communication capable of simplifying its assembling process and enhancing its assembly precision and performance by constructing an exciter consisting of a conductor pattern on a high frequency circuit board, and forming the shield case of a high frequency circuit into a prescribed shape thereby attaching case to a main board. SOLUTION: An exciter 47 for impedance conversion is constructed by forming a conductor pattern 46 on the surface of one end together with a high frequency circuit part 45 on a high frequency circuit board 42 provided on one edge side of a main board 41 and is connected to the part 45 by means of a printed circuit. A shield case 48 of the part 45 is provided with attaching legs 49 to 51, the leg 51 is passed through the board 42, its lower end is attached to the substrate 41 and the board 42 is fixed in such a manner that it floats slightly from the main board. Thus, the work that separately fixes and connects the exciter 47 is unnecessitated to facilitate the connection of an antenna, the board 42 is stably fixed to the substrate 41 in all of the directions to enhance assembly precision, thereby improving its connection characteristics to the antenna.</p> |
