“…In wireless communication, reconfigurable components are increasingly important due to their ability to tune it by external stimuli, such as magnetic fields and thermal, electrical, mechanical, and optical factors . For example, smartphones contain multiple antennas that are usually implemented to cover different frequency bands (working frequency determines antenna length), such as global positioning system (GPS), global system for mobile communication (GSM), Wi‐Fi, Bluetooth, 2G/3G, or 4G long‐term evolution (LTE).…”

phase-change temperature. In addition, VO 2 also possesses different polymorphisms, including VO 2 (A), [6] VO 2 (B), [7,8] VO 2 (D), [9] VO 2 (M), [10] VO 2 (R), [11] and VO 2 (P). [12] Among them, the VO 2 monoclinic (M) phase is the most attractive due to its MIT behavior at a relatively low temperature of 68 °C. [13] However, the simultaneous creation of polymorphs results in a mixture phase and makes it extremely difficult to achieve a pure VO 2 (M) phase. The MIT temperature of VO 2 (M) can also be further reduced by doping [14] and by varying the particle sizes. [10,12] This makes VO 2 a promising material for many practical applications, including sensors, [15] thermochromic smart windows, [16] field effect transistors, [17] radio-frequency (RF) switches, [18] terahertz nanoantennas, [19] reconfigurable antennas, [20] memory, [21] and energy. [22,23] Due to the exciting applications mentioned above, considerable effort has been devoted to producing VO 2 (M) in the form of a thin film, primarily with a dry vapor process using chemical vapor deposition, [24] sputtering, [25] metalorganic molecular beam epitaxy deposition, [26] pulsed laser deposition, [27,28] e-beam evaporation, [29] and by electric field inducing ions migration. [30] On the other hand, several bulk nanomaterials in solution processes with different shapes and sizes using sol-gel [31] and hydrothermal synthesis [32] are reported. The VO 2 thin-film deposition techniques using dry vapor processes require an ultrahigh level of vacuum conditions (10 −6 Torr) and sometimes very high processing temperatures (400-600 °C). The process also requires expensive masks and nanolithography for device prototyping. However, the solution-based VO 2 preparation processes are the simplest, require lower processing temperatures, and are highly scalable. Among the solution-based processes, hydrothermal synthesis is the most widely adopted technique due to its high-quality and purephase VO 2 nanomaterial production. [5] The only disadvantage of hydrothermal synthesis is the longer reaction time required, up to 2-4 d, to achieve pure VO 2 (M). For practical applications, VO 2 (M) nanostructures must be deposited in the form of films. Spin coating is one technique to realize VO 2 films, but large-area processing and direct patterning are not possible. [31] With the surge in inkjet printing, which is extremely low cost, completely digital, and highly suitable for rapid prototyping or large-scale manufacturing, realizing VO 2 film through inkjet The metal-insulator transition (MIT) phase change of vanadium dioxide (VO 2 ) materials has facilitated many exciting applications. Among the various crystal phases of VO 2 , the monoclinic (M) phase is the only one that demonstrates low-temperature (≈68 °C) MIT behavior. However, the synthesis of pure VO 2 (M) is challenging because various polymorphs, such as VO 2 (A), VO 2 (B), and VO 2 (D), are also typically formed during the process. Furthermore, to achieve pure crystalline VO 2 (M) phase, very long reaction times, up...

MEMS switch is a movable device manufactured by means of semiconductor technology, possessing many incomparable advantages such as a small volume, low power consumption, high integration, etc. This paper reviews recent research of MEMS switches, pointing out the important performance indexes and systematically summarizing the classification according to driving principles. Then, a comparative study of current MEMS switches stressing their strengths and drawbacks is presented, based on performance requirements such as driven voltage, power consumption, and reliability. The efforts of teams to optimize MEMS switches are introduced and the applications of switches with different driving principles are also briefly reviewed. Furthermore, the development trend of MEMS switch and the research gaps are discussed. Finally, a summary and forecast about MEMS switches is given with the aim of providing a reference for future research in this domain.

“…Conventional reconfigurable antennas typically employ techniques such as radio frequency (RF) switches such as PIN diodes [ 1 , 7 ] and varactors [ 8 ]. Besides that, microelectromechanical system (MEMS) switches, which offer high isolation and low insertion loss [ 9 ] are also becoming popular, whereas PIN diodes are ideal for fast switching [ 10 ] and varactor diodes provide continuous tuning ability [ 11 ]. Despite being achievable using RF switches, the reconfigurability feature in antennas can also be implemented using conductive fluids such as liquid metal (LM), ionized water, and dielectric fluids such as ethyl acetate and deionized (DI) water.…”

Advances in reconfigurable liquid-based reconfigurable antennas are enabling new possibilities to fulfil the requirements of more advanced wireless communication systems. In this review, a comparative analysis of various state-of-the-art concepts and techniques for designing reconfigurable antennas using liquid is presented. First, the electrical properties of different liquids at room temperature commonly used in reconfigurable antennas are identified. This is followed by a discussion of various liquid actuation techniques in enabling high frequency reconfigurability. Next, the liquid-based reconfigurable antennas in literature used to achieve the different types of reconfiguration will be critically reviewed. These include frequency-, polarization-, radiation pattern-, and compound reconfigurability. The current concepts of liquid-based reconfigurable antennas can be classified broadly into three basic approaches: altering the physical (and electrical) dimensions of antennas using liquid; applying liquid-based sections as reactive loads; implementation of liquids as dielectric resonators. Each concept and their design approaches will be examined, outlining their benefits, limitations, and possible future improvements.
