MEMS resonators have stimulated an increasing interest within the last years, and many applications of this technology in fields such as telecommunications, inertial sensors, as well as biosensors, have been demonstrated. The achievement of a high quality factor (Q factor) for these devices is a key issue to maximize their performance. Therefore, there is a continuous search for the structure and...
In this work, highly selective filters based on periodic arrays of electrically small resonators are pointed out. The high-pass filters are implemented in microstrip technology by etching complementary split ring resonators (CSRRs), or complementary spiral resonators (CSRs), in the ground plane, and series capacitive gaps, or interdigital capacitors, in the signal strip. The structure exhibits a composite...
In this paper the most relevant applications derived from dispersion and impedance engineering in resonant type metamaterial transmission lines are highlighted. Essentially, this includes enhanced bandwidth components and dual-band components. Due to the small electrical size of the considered metamaterial resonators, size reduction is also obtained. We will provide some recent results obtained by...
