“…An SLA process based on epoxy was used to generate the structure, and then a Cu-plating step was added. While the return loss was not verified in [114], the authors reported >25 dBi peak directivity at 12 GHz. In [115], a 2 × 2 horn antenna array utilized the design freedom of SLA to minimize insertion losses to 34 dB along the main radiation axis, while demonstrating a 24 dBi directivity from 26 to 40 GHz.…”

“…The first demonstration of a Yagi-Uda antenna was done a year earlier using IJP Ag (1.1 × 10 7 S/m) and SU-8 dielectric (ε = 3.2, tanδ = 0.04) on a liquid crystalline polymer laminate substrate that has a high 8 dBi gain at 24.5 GHz with a >33 dB S 11 [92]. Several horn-type antennas have also been demonstrated with the best performance going to a hybrid printing and plating process [114,115]. An SLA process based on epoxy was used to generate the structure, and then a Cu-plating step was added.…”

Printing methods such as additive manufacturing (AM) and direct writing (DW) for radio frequency (RF) components including antennas, filters, transmission lines, and interconnects have recently garnered much attention due to the ease of use, efficiency, and low-cost benefits of the AM/DW tools readily available. The quality and performance of these printed components often do not align with their simulated counterparts due to losses associated with the base materials, surface roughness, and print resolution. These drawbacks preclude the community from realizing printed low loss RF components comparable to those fabricated with traditional subtractive manufacturing techniques. This review discusses the challenges facing low loss RF components, which has mostly been material limited by the robustness of the metal and the availability of AM-compatible dielectrics. We summarize the effective printing methods, review ink formulation, and the postprint processing steps necessary for targeted RF properties. We then detail the structure-property relationships critical to obtaining enhanced conductivities necessary for printed RF passive components. Finally, we give examples of demonstrations for various types of printed RF components and provide an outlook on future areas of research that will require multidisciplinary teams from chemists to RF system designers to fully realize the potential for printed RF components.

“…In the literature, few AM built horn antennas have been reported so far [1][2][3][4]. All these antennas use stereolithography apparatus (SLA) method to be fabricated instead fused deposition modeling (FDM) as is in this work reported.…”

In this paper, the design, fabrication, and test of an additive manufactured double-ridged horn antenna optimized to work in ultra-wide-band frequencies is introduced. In particular, to build this antenna, the fused deposition modeling fabrication method is selected. The plastic-made device is then coated by using conductive ink. The double-ridged horn is conceived as a monolithic block. In this way, performance degradations caused by fabrication inaccuracies are minimized. A very good agreement between the simulations and the antenna measurements is demonstrated. The proof-ofconcept prototype has an outstanding operational bandwidth performance of 11.5 GHz (fc 8.25 GHz) with a gain of 6 dBi; its total weight is less than 200 gr, and the total prototyping fabrication costs are less than 10 Euro per antenna with a lead time of less than a week.

“…Ring-focus parabolic antenna overcomes feed shelter to realize low sidelobes and VSWR in a broad bandwidth and has been applied widely in VSAT. The antenna can enhance its efficiency by changing the shape of hat feed [28], reducing its size by using a spline-profiled smooth horn [29], and improving its performance on VSWR and crosspolarization via a small ring-shaped aperture [30]. But all the schemes above have low efficiency due to the support for subreflector.…”

A design for Ka-band satellite communication antenna in earth station is introduced. This kind of antenna uses splash plate feed based on ring-focus antenna. The theory of the new splash plate feed design is presented and the relative equations are derived. The measured antenna parameters, VSWR, and patterns are highly consistent with the simulated results, which demonstrates the success of the design for such kind of antenna that can be effectively used in Ka-band applications.
