Microsystem technology for high frequency applications is a well-established research field for a huge number of microwave to millimeter wave tunable devices and subsystems. Applications encompass ground and space architectures for signal routing, RADAR systems, radio-link communications, satellite reconfiguration, and redundancy purposes. The main advantages are related to an all-passive architecture overwhelming the typical drawbacks of semiconductor devices, like diodes in digital signal processing, with no signal distortion and very low-level losses. The main open issues, i.e., reliability, power handling, packaging, and integration, and charging effect limitations were effectively addressed across the last 10–15 years, making RF-MEMS technology readiness compatible with commercial applications.
Recently, several configurations have been developed using advanced technological solutions to make both analog and digital signal processing possible, with a lifetime extended to more than ten years, making high frequency microsystems appealing again even for long-term applications. Moreover, novel design approaches are contaminating classical microsystem configurations with a possible extension towards miniaturization and smart functionalities, useful in perspective also for 5G and IOT structures, including micro- and nano-systems, i.e., MEMS and NEMS. Additional capabilities can also relate to sensing and microfluidics.
The current focus is to develop components for signal transmission and irradiation subsystems in the K (18–26.5 GHz), Ka (26.5–40 GHz), and Q (33–50 GHz) bands, which are of great interest for RADAR and telecommunications via satellite. The main purpose is to determine the technological solutions suitable for wide band performance, easily reconfigurable and with superior miniaturization capabilities of passive components.
In this Special Issue, research papers, short communications, and review article contributions are welcome in describing the state-of-the-art for design, technology, and test protocols for high frequency microsystems.
