ANTENNA MODULE AND PORTABLE DEVICE USING IT

摘要

PROBLEM TO BE SOLVED: To achieve sufficient antenna performance without the need for taking the layout into account. SOLUTION: The antenna module is provided with an antenna core 12, a conductor 11 wound on the antenna core 12, a variable capacitance diode 13 mounted on a printed circuit board 30 and connected in parallel with both ends of the conductor 11, a ground terminal 17 to which one terminal of a parallel connector 14 connected in parallel, and an output terminal 24 to which the other terminal of the parallel connector 14 is connected, and the printed circuit board 30 is pressed into contact with an upper side of the antenna core 12 and integrally formed.
