Abstract
To provide a compact antenna capable of corresponding to a plurality of frequency bands. In a first frequency characteristic adjustment unit, the susceptance thereof varies according to a frequency of an input signal. A second frequency characteristic adjustment unit is connected to the first frequency characteristic adjustment unit and the reactance thereof varies according to the frequency of the input signal. A third frequency characteristic adjustment unit is connected to the second frequency characteristic adjustment unit, the susceptance thereof varies according to the frequency of the input signal. A feeding unit is configured to input a signal of any frequency in a plurality of different frequencies to the second frequency characteristic adjustment unit. A sign of the reactance of the second frequency characteristic adjustment unit at the frequency of the signal input from the feeding unit is the same as those of the susceptances of the first frequency characteristic adjustment unit and the third frequency characteristic adjustment unit.
