Patent ID: 7345651

Claim:
An antenna attachable to a receiver for selectively receiving radio waves of two or more frequency bands, the antenna having a first end connectable to the receiver and a second end, said antenna comprising: a plurality of conducting wires connected in series; and at least one inductor inserted between the plurality of conducting wires, wherein a length from the first end to the second end of the antenna and a length from the first end to a position where one of the inductors is connected are n/4 (n represents 1, 2, 3 or 4) of a wavelength at a center frequency of one of the two or more frequency bands or a frequency around the center frequency, and the at least one inductor has a self-resonant frequency matching with the center frequency of the frequency band corresponding to the length from the first end to the position where the inductor is connected or matching with a frequency around the center frequency.
