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 ...
Phase noise of −150 dBc at 10 kHz from 10 MHz is now available, a level that is generally only needed for radio frequency (RF) applications. MEMS oscillators are now available with integrated jitter under 1.0 picosecond, measured from 12 kHz to 20 MHz, a level that is normally required for high speed serial data links, such as SONET and SyncE ...
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.
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 ...
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 ...

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 ]
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.
