Abstract
A matching device for an antenna in which is interposed between an antenna of narrow frequency band and a feeding line so as to match the antenna and the feeding line over a wide band, includes a high impedance line of a first predetermined length provided at the antenna side and a low impedance line of a second predetermined length provided at the feeding line side that are connected in series, whereby the matching device can be made small in size and simple in construction.
