“…[4] The CRLH NLTLs have been proved to be a typical planar transmission line implementation of metamaterial, [3,14] compatible with the standard GaAs monolithic microwave integrated circuit (MMIC) technology, Si technology, and printed circuit board designs, [15] which show low-loss and broad-bandwidth performances and widely obtain microwave applications. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Some attempts have been made to design the MMIC harmonic generator. [16,17] When compared with a frequency multiplier based on an FET, [19,20] one based on CRLH NLTLs is self-matched over a much wider frequency range and no additional matching network and filter are needed.…”

A bandwidth microwave second harmonic generator is successfully designed using composite right/left-handed nonlinear transmission lines (CRLH NLTLs) in a GaAs monolithic microwave integrated circuit (MMIC) technology. The structure parameters of CRLH NLTLs, e.g. host transmission line, rectangular spiral inductor, and nonlinear capacitor, have a great impact on the second harmonic performance enhancement in terms of second harmonic frequency, output power, and conversion efficiency. It has been experimentally demonstrated that the second harmonic frequency is determined by the anomalous dispersion of CRLH NLTLs and can be significantly improved by effectively adjusting these structure parameters. A good agreement between the measured and simulated second harmonic performances of Ka-band CRLH NLTLs frequency multipliers is successfully achieved, which further validates the design approach of frequency multipliers on CRLH NLTLs and indicates the potentials of CRLH NLTLs in terms of the generation of microwave and millimeter-wave signal source.

“…Electronic devices are a clear example of this; they have evolved from very simple structures to complete systems being fabricated on chip. Nowadays, two emerging technologies with a wide application in electronics are metamaterials [1][2][3][4][5] and microelectromechanical systems (MEMS). Using these in conjunction allows us to design and fabricate a plethora of new devices, especially in the �eld of high-frequency electronics, which is increasingly in demand.…”

This paper presents the design of a novel, small coplanar antenna using microelectromechanical systems (MEMS) and metamaterial (MTM) properties. The antenna is designed using coplanar waveguide (CPW) technology, presenting lower dielectric losses and higher signal integrity. The design method for this MEMS-MTM antenna, herein presented, is based on a composite right/left hand (CRLH) transmission Line (TL) using a mixed approach; considering the circuit model and full-wave simulations. The fabrication process is based on high-resistivity silicon wafers. The radiator has dimensions of0.017 λg×0.033 λgand a thickness of0.0116 λg, whereas the complete circuit, of 5 mm × 11 mm, is equivalent to0.14 λg×0.31 λg. The antenna is designed using MEMS parallel-plate capacitors as the radiator, which also allows for the reconfiguration of the central frequency by electrostatically varying the capacitance. The results presented here correspond to a central frequency of 8.4 GHz. Due to its small size, this antenna has a wide variety of applications in wireless circuits for different fields.
