This paper presents a novel high-frequency filter concept based on a single MEMS capacitive shunt structure using meander arm inductance. Tuning ranges of the central frequency in the order of 55% are experimentally demonstrated for filters operating between 13.5 GHz to 30 GHz and 17 GHz to 37 GHz. A low transmission loss of 0.44 dB and a rejection level of -20.5 dB at 17 GHz are reported. The outstanding...
This paper explores the design and fabrication of Micro-Electro-Mechanical capacitors based on vertical carbon nanotube arrays. The devices are realized in vertically single-clamped parallel plate configurations using a dense array of vertically grown MWCNTs on metal lines. The capacitance tuning is performed by electrostatic actuation. From the pull-in voltage value, based on novel analytical model...
This paper reports on the potential of RF-MEMS technology to improve and miniaturize new functions in Radar front end and antenna modules. The insertion of new MEMS components and subsystems, using RF-MEMS switches, filters and phase shifters, in radar front end are reported in this article and their characterization results are discussed.
This paper presents a novel tunable bandpass filter design with independent control of both the centre frequency and the bandwidth by means of analogue-series and digital-shunt MEMS capacitors. The filter is designed for operation in X and Ku bands with 4 pre-selected centre frequencies (from 10 GHz to 14 GHz) and with a bandwidth tunability of 70% (variable between 500 MHz and 1 GHz). The filter...
