Summary Harmonic resonance is characterized in a composite right‐handed and left‐handed (CRLH) transmission line periodically loaded with Schottky varactors, termed a Schottky CRLH line, to achieve efficient second harmonic generation. CRLH line dispersion can cause the second harmonic wave to have the same phase velocity as the fundamental. Application of such fundamental wave enables its second harmonic to develop spontaneously. Both the fundamental and second harmonic waves can gain amplitudes as their phases advance owing to left‐handedness so that a second harmonic of significant amplitude can be obtained with the aid of cavity resonance. In this study, we discuss the design criteria for a Schottky CRLH line as a platform for second harmonic generation based on harmonic resonance. Copyright © 2015 John Wiley & Sons, Ltd.
