By utilizing a cross-junction-loaded rectangular hole as a defected ground structure (DGS) at the input side and a simple slotline-based defected ground at the output side, a novel microwave frequency tripler with conversion gain is demonstrated. The cross-junction-loaded hole at the input side acts as a reflector with the capability of providing a suitable reflection for the 3rd harmonic and improving the output power; it also maintains a good pass-band performance at the fundamental frequency f(0). The slotline-based DGS functions as a frequency selector and diminishes unwanted harmonic components at f0, 2f(0), 4f(0), and 5f(0) while only passing the desirable multiplied frequency component (3f(0)). With proper DC bias conditions, results from measurements indicate that the developed tripler achieves an approximate conversion gain of 0.9 dB at 3f(0) under an optimal input power of 2 dBm.
