Special Issue Information

Dear Colleagues,

RF MEMS is a type of MEMS device that processes radio frequency signals. RF MEMS can utilize MEMS technology to manufacture on-chip transmission lines, RF cavities, three-dimensional inductors, couplers, varactors, switches, filters, phase shifters and antennas. Compared with traditional RF devices, RF MEMS devices have many advantages, including their small size, insensitivity to acceleration, low DC power consumption, and ability to be fabricated on low-cost silicon or glass substrates. In addition, RF MEMS devices can be integrated with traditional silicon-based and gallium arsenide-based circuits, enabling miniaturization of RF processing systems. These advantages have led to significant applications in fields such as mobile communications, satellites, radars, etc. Accordingly, this Special Issue seeks to showcase research papers, short communications, and review articles that focus on novel technology and progress in RF MEMS and its use for various RF systems.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Due to the high gain, wide bandwidth, and directional radiation characteristics of Vivaldi antennas, this paper conducted relevant research on the feasibility of non-destructive blood glucose detection based on Vivaldi antennas. The research included finite element method (FEM) simulation and glucose concentration monitoring. In the simulation stage, the power transmission and reflection characteristics, radiation characteristics, and electric field distribution characteristics of the antenna were described in detail. In the test stage, the S11 response of the antenna to variation in glucose concentration in the range of 0–6.11 mg/mL was measured, including the S11 amplitude and phase. The experimental results show that there is a high linear correlation between the S11 response and glucose concentration, and the sensitivity of the S11 amplitude response to the variation in glucose concentration is close to 0.3445 (dB/(mg/mL)) at 14.2556 GHz, and the sensitivity of the S11 phase response to the variation in glucose concentration is about 0.5652 (degree/(mg/mL)) at 14.37 GHz. In addition, the predicted results of the glucose concentration based on linear regression are discussed. Full article
