Tunability of Piezoelectric MEMS Ring Resonator Based Filter

The influence of piezoelectric actuator design on a two-port piezoelectrically transduced micro-electro-mechanical (MEMS) ring resonator frequency tuning performance has been investigated. A cubic silicon carbide (3C-SiC) ring resonator was fabricated with a lead–zirconium–titanate (PZT) piezoelectric actuator and sensor integrated on the surface of the ring. Measurements of the transmission fr...

Reconfigurable Antenna Structures Using Mems Technology

The tunable characteristics of RF MEMS (Microelectromechanical Systems) components enable their integration with antennas providing numerous advantages such as reconfigurability in polarization, frequency, and radiation pattern [1]. Furthermore, the monolithic fabrication of these components with antennas can reduce parasitic effects, losses and costs. This paper presents two tunable frequency ...

Fabrication and Modeling of Piezoelectric RF MEMS Resonators

Resonators serve as essential components in radio-frequency (RF) electronics, forming the backbone of filters and tuned amplifiers. However, traditional solid state or mechanic implementations of resonators and filters tend to be bulky and power hungry, limiting the versatility of communications, guidance, and avionics systems. Microelectro-mechanical systems (MEMS) are promising replacements f...

Phased array antenna using MEMS phase shifter

This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...

Combining SGBEM and FEM for modeling 3D cracks

The SGBEM-FEM alternating method suitable for the solution of elastic and elasticplastic three-dimensional fracture mechanics problems is presented. The crack is modeled by the symmetric Galerkin boundary element method (SGBEM), as a distribution of displacement discontinuities in an infinite medium. The finite element method (FEM) is used for stress analysis of the uncracked finite body. The s...
