Harmonic Reduction Amplifier using ?/4 High Impedance Bias Line with Defected Ground Structure (DGS)
In this paper, a new defected ground structure (DGS) λ /4 bias line that dumbbell-shaped ground pattern is etched on ground plane of microstrip line is proposed. This DGS λ /4 bias line maintains high impedance, but physical width is wider and length is shorter than that of the conventional bias line.
