Abstract
A transmission line substrate comprises: a dielectric substrate; a signal line formed on the upper surface of the dielectric substrate; first and second ground conductors formed on the upper surface of the dielectric substrate, field-coupled to the signal line, having potentials different from each other; a dielectric film formed between a part of the overlapping first ground conductor and a part of the second ground conductor to constitute a MIM capacitor; a capacitor connected between the first ground conductor and the second ground conductor in parallel with the dielectric film; and a resistor connected between the first ground conductor and the second ground conductor in series with the capacitor.
