Abstract:
A method for forming a small low-posture antenna which is tuned near a wavelength &lgr;, wherein an antenna pattern which resonates at &lgr;/4 is formed on a surface of a substrate, wherein the substrate is made to oppose and is supported with respect to a planar portion of a metallic frame, wherein a helical coil which resonates at &lgr;/4 is supported by the metallic frame, wherein one end of the antenna pattern is connected to and is brought into electrical conduction with the metallic frame, and wherein one end of the helical coil and one end of the antenna pattern are made to oppose each other in order to provide capacitance and the other end of the helical coil is connected to an output end of a high-frequency circuit in order to make the helical coil act as an antenna exciter.
