Study and Analysis of Rf Mems Shunt Switch for Reconfigurable Antenna
RF MEMS switches can be used to achieve reconfigurability of various RF systems and in particularly for miniaturized antenna structures. In case of micro machined antennas, which involve low voltage signals, RF MEMS switches with low actuation voltage are required for achieving reconfigurability. The capacitive shunt switch derives its switching property from the significant difference of its c...
متن کاملStudies on RF MEMS shunt switch
Radio Frequency Micro-Electro-Mechanical-Systems (RF MEMS) based switches are expected to play a key role in the field of microwave switching. Traits like low-loss performance; zero-power consumption and very low inter-modulation distortion have made these switches well suitable for high-performance microwave and millimeter-wave circuits. The design of RF MEMS switches, however, require sophist...
متن کاملDesign and simulation of a RF MEMS shunt capacitive switch with low actuation voltage, low loss and high isolation
According to contact type, RF MEMS switches are generally classified into two categories: Capacitive switches and Metal-to-Metal ones. The capacitive switches are capable to tolerate a higher frequency range and more power than M-to-M switches. This paper presents a cantilever shunt capacitive RF MEMS switch with characteristics such as low trigger voltage, high capacitive ratio, short switchin...
متن کاملMaterial Selection of Rf-mems Switch Used for Reconfigurable Antenna Using Ashby’s Methodology
This paper reports material selection methodology for radio frequency — micro electro mechanical systems (RF-MEMS) switches used for reconfigurable antennas. As there are variety of materials available to design engineer, a proper technique to select the best possible material is needed. Three primary performance indices, pull-in voltage, RF-loss, and thermal residual stress, are used to obtain...
متن کاملReconfigurable Microstrip Patch Antenna for Frequency Diversity Using RF MEMS
Abstract: A novel reconfigurable patch antenna for frequency diversity is proposed by reconfiguring its geometry using tree rectangular tapes that are connected to the patch via six RF MEMS switches. So switching between the different frequency bands is achieved by using capacitive series RF-MEMS switches. The antenna was designed to operate at 2.6 GHz, 3.1 GHz, 3.5 GHz and 5 GHz.
