ABSTRACT:
A closed loop is formed by loop antenna elements which equivalently function as inductance, a capacitor inserted in such a manner as to divide the loop antenna into the loop antenna elements, and an impedance-matching dividing element for tuning the antenna and establishing matching with a high-frequency circuit side. A subsidiary substrate with the capacitor mounted thereon is fixedly installed by a retaining pawl of an antenna holder, and is connected to the loop antenna elements by being soldered thereto at a pair of lands on the subsidiary substrate. As a result, it is possible to improve the effective gain of the antenna and effectively utilize the substrate space.
