“…Over the past few years, these MJ techniques have attracted interest in the on-demand fabrication of highly customizable electronics because of their abilities to precisely and smartly deliver high-resolution patterns with a diversified structure (<1 µm) from design files in a non-contact manner. Multi-material 3D printing of supercapacitors [ 26 ], filters [ 27 ], tapered optical waveguides [ 28 ], solar cells [ 29 ], microsensors [ 30 ], flexible circuits [ 31 ], and high-density redistribution layers (RDLs) of silicon interposers [ 32 ] has been easily implemented by following the same approach of conventional 2D ink jetting by sequential deposition of functional inks via an MJ system equipped with multiple jetting heads. Table 1 lists several recently developed functional inks whose printing methods, applications, sintering or curing techniques, and electrical properties are summarized.…”

In recent years, functional ceramic devices have become smaller, thinner, more refined, and highly integrated, which makes it difficult to realize their rapid prototyping and low-cost manufacturing using traditional processing. As an emerging technology, multi-material 3D printing offers increased complexity and greater freedom in the design of functional ceramic devices because of its unique ability to directly construct arbitrary 3D parts that incorporate multiple material constituents without an intricate process or expensive tools. Here, the latest advances in multi-material 3D printing methods are reviewed, providing a comprehensive study on 3D-printable functional ceramic materials and processes for various functional ceramic devices, including capacitors, multilayer substrates, and microstrip antennas. Furthermore, the key challenges and prospects of multi-material 3D-printed functional ceramic devices are identified, and future directions are discussed.

In the last decade, the filter community has innovated both design techniques and the technology used for practical implementation. In design, the philosophy has become "if you can't avoid it, use it", a very practical engineering approach. Modes previously deemed spurious are intentionally used to create in-line networks incorporating real or imaginary transmission zeros and also reduce the number of components and thus further miniaturize; spurious responses are re-routed to increase the passband width or stopband width, frequency variation in couplings is used to create complex transfer functions, with all of these developments using what was previously avoided. Clever implementations of baluns into passive and active networks is resulting in a new generation of noise-immune filters for 5G and beyond. Finally, the use of a diakoptic approach to synthesis has appeared an evolving approach in which small blocks ("singlets", "doublets", etc.) are cascaded to implement larger networks, (reducing the need for very complex synthesis), with this new approach promising a large impact on the implementation of practical structures. Filter technology has migrated towards "observe it and then adapt it", pragmatically repurposing tools not specifically originally intended for the applications. Combinations of surface wave and bulk wave resonators with L-C networks are improving the loss characteristics of filters in the region below 2 GHz. Lightweight alloys and other materials designed for spacecraft are being used in filters intended for space, to provide temperature stability without the use of heavy alloys such as Invar. Fully-enclosed waveguide is being replaced in some cases by planar and quasiplanar structures propagating quasi-waveguide modes. This is generically referred to as SIW (Substrate Integrated Waveguide). Active filters trade noise figure for insertion loss but perhaps will offer advantage in terms of size and chip-level implementation. Finally, the era of reconfiguration might be approaching, as the basic networks are evolving, perhaps lacking only the appearance of lower-loss, higher-IP solid-state tuning elements.

“…Additive manufacturing processes enable high low-to-medium, low cost, and versatile fabrication through the deposition of functional materials on the required location [18]. Motivated by these advantages, researchers have demonstrated some printed filters [19]- [22], however, none of them shows any reconfigurability. Some printed filters have been shown which are also reconfigurable but the switch or the switching mechanism has not been printed [23].…”

Modern wireless devices operate on multiple frequency bands, and thus can benefit from frequency reconfigurable Radio Frequency (RF) components, especially filters as they are typically larger in size and are required for every frequency band. In addition, many applications such as wearable electronics, desire stable performance from the devices when they are bent or flexed. However, most of the reconfigurable filters are built on rigid substrates and utilize expensive discrete RF switches, which need to be soldered to the filters. In this work, we present a fully printed filter that achieves reconfigurability through printed Vanadium Dioxide (VO2) based switches, which are extremely low cost and do not require any soldering for their attachment. The filter design is based on a dual-mode resonator which enables a second-order filter despite a single resonator, thus helping in making the filter compact. It also helps in maintaining a decent insertion loss (2.6 dB), despite relatively low conductivity of the metallic ink. The switches, when activated thermally through a printed heater at the backside, reconfigure the frequency from 4 GHz to 3.75 GHz. The filter has been realized on a flexible Kapton substrate, making the filter conformable to any surface. Measurements under various bending conditions reveal stable performance, making this filter design suitable for a number of wearable and Internet of Things applications.
