Design 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 کاملDesign of a V-band Phase Shifter Using SP4T RF-MEMS Switches with Sonnet
This paper presents the design of a V-band switched-line phase shifter using SP4T RF-MEMS switches. Sonnet simulations are used to achieve accurate circuit models of both the RF-MEMS switches as well as CPW bends within the phase shifter. The V-band phase shifter utilizes two SP4T RF-MEMS switches to perform the delay line switching. The RF performance of the SP4T MEMS switch is optimized to ad...
متن کاملDesign, Analysis, and Verification of Ka-Band Pattern Reconfigurable Patch Antenna Using RF MEMS Switches
Abstract: This paper proposes a radiating pattern reconfigurable antenna by employing RF Micro-electromechanical Systems (RF MEMS) switches. The antenna has a low profile and small size of 4 mm× 5 mm× 0.4 mm, and mainly consists of one main patch, two assistant patches, and two RF MEMS switches. By changing the RF MEMS switches operating modes, the proposed antenna can switch among three radiat...
