This paper presents the design and implementation of a reconfigurable reflectarray element design using commercially available RF MEMS switches. This reconfigurablity allows for dynamic control of individual radiating elements by electronically manipulating the switch configuration. The reflectarray element chosen here consists of a microstrip patch on the top surface with a slot in the ground ...

This paper reports on the design of a novel ultra low actuation voltage, low loss radio frequency micro-electro-mechanical system (RF MEMS) capacitive shunt switch. The concept of the switch relies on a mechanically unconstrained armature actuated over a coplanar waveguide using electrostatic forces. The minimum actuation voltage of the switch is <2V, with an isolation of 40dB and insertion los...

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...

MEMS technology offers some unique product opportunities for optical networking applications. One of the critical factors that determine the commercial success of any optical MEMS components is the cost for packaging and optical fiber alignment. Small form factor MEMS components such as protection switches and variable optical attenuators require the integration of optical fibers and lenses wit...
