    The prior art includes an RF MEMS frequency tunable fractal antenna for the 0.1–6 GHz frequency range, [18] and the actual integration of RF MEMS switches on a self-similar Sierpinski gasket antenna to increase its number of resonant frequencies, extending its range to 8 GHz, 14 GHz and 25 GHz, [19] [20] an RF MEMS radiation pattern ...

  3. Microelectromechanical system oscillator - Wikipedia

    en.wikipedia.org/wiki/Microelectromechanical...

    MEMS clock generators are MEMS timing devices with multiple outputs for systems that need more than a single reference frequency. MEMS oscillators are a valid alternative to older, more established quartz crystal oscillators, offering better resilience against vibration and mechanical shock, and reliability with respect to temperature variation.

    MEMS microcantilever resonating inside a scanning electron microscope Proposal submitted to DARPA in 1986 first introducing the term "microelectromechanical systems". MEMS (micro-electromechanical systems) is the technology of microscopic devices incorporating both electronic and moving parts.

  6. Microoptoelectromechanical systems - Wikipedia

    en.wikipedia.org/wiki/Microoptoelectromechanical...

    In 1993, Dr. Motamedi officially introduced MOEMS for the first time, as the powerful combination of MEMS and micro-optics, in an invited talk at the SPIE Critical Reviews of Optical Science and Technology conference in San Diego. In this talk Dr. Motamedi introduced the figure below, for showing that MOEMS is the interaction of three major ...

  7. Reconfigurable antenna - Wikipedia

    en.wikipedia.org/wiki/Reconfigurable_antenna

    A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. [2] In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ...

  8. Microfabrication - Wikipedia

    en.wikipedia.org/wiki/Microfabrication

    Microforming is a microfabrication process of microsystem or microelectromechanical system (MEMS) "parts or structures with at least two dimensions in the submillimeter range." [ 3 ] [ 4 ] [ 5 ] It includes techniques such as microextrusion , [ 4 ] microstamping , [ 6 ] and microcutting. [ 7 ]

  9. Radio frequency - Wikipedia

    en.wikipedia.org/wiki/Radio_frequency

    Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency [1] range from around 20 kHz to around 300 GHz.
