Abstract
A conductor line is formed on the upper side of a dielectric plate, and a ground electrode is formed on the underside. Further, electrode non-formation portions are distributed at intervals a in the propagation direction of a signal and at intervals b in the perpendicular direction to the propagation direction. A band-stop or low-pass filter characteristic is produced by increasing the transmission loss in a frequency band determined by the intervals a, and the attenuation in the stop-band is determined by the intervals b in the width direction.
