“…There are two widely used 3D-printing techniques [53][54][55][56][57][58][59][60][61]: polymer/dielectric and all-metal. As the working frequency band enters the millimeter/microwave range, the printed parts' quality for the resulting antenna is of great importance.…”

In this study, the effects of graphene and design differences on bow-tie microstrip antenna performance and bandwidth improvement were investigated both with simulation and experiments. In addition, the conductivity of graphene can be dynamically tuned by changing its chemical potential. The numerical calculations of the proposed antennas at 2–10 GHz were carried out using the finite integration technique in the CST Microwave Studio program. Thus, three bow-tie microstrip antennas with different antenna parameters were designed. Unlike traditional production techniques, due to its cost-effectiveness and easy production, antennas were produced using 3D printing, and then measurements were conducted. A very good match was observed between the simulation and the measurement results. The performance of each antenna was analyzed, and then, the effects of antenna sizes and different chemical potentials on antenna performance were investigated and discussed. The results show that the bow-tie antenna with a slot, which is one of the new advantages of this study, provides a good match and that it has an ultra-bandwidth of 18 GHz in the frequency range of 2 to 20 GHz for ultra-wideband applications. The obtained return loss of −10 dB throughout the applied frequency shows that the designed antennas are useful. In addition, the proposed antennas have an average gain of 9 dBi. This study will be a guide for microstrip antennas based on the desired applications by changing the size of the slots and chemical potential in the conductive parts in the design.

“…The advantage of SLA printing in antenna manufacturing is that it achieves a higher degree of detail, layered printing, and surface quality. The center frequency of the proposed antenna was obtained to be 77 GHz with a bandwidth of about 20 percent as a result of a simulation [14]. Sarjoghian et al [15] proposed a 3D-printed pyramidal double-ridged horn antenna filled with high-dielectric material.…”

“…Substrate materials with a low thickness value are widely preferred as they provide improved performance, enhanced bandwidth, and less restricting structures for radiation areas. Various techniques are utilized to manufacture MAs, including wet-etching, inkjet printing, screen printing, and threedimensional (3D) printing [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. 3D printing has a promising potential in antenna manufacturing as it allows faster, more convenient, and less expensive manufacturing than the conventional tech techniques, known as additive manufacturing [10,11].…”

This paper proposes a novel and compact monopole microstrip antenna (MA) design with a three-dimensional (3D) printed curved substrate for biomedical applications. A curved substrate was formed by inserting a semi-cylinder structure in the middle of the planar substrate consisting of polylactic acid (PLA). The antenna was fed with a microstrip line, and a partial ground plane was formed at the bottom side of the substrate. The copper plane with two triangular slots is arranged on the curved semi-cylinder structure of the substrate. The physical dimensions of the radiating plane and ground plane were optimally determined with the use of the sparrow search algorithm (SpaSA) to provide a wide -10 dB bandwidth between 3 GHz and 12 GHz. A total of six microstrip antennas having different parameters related to physical dimensions were designed and simulated to compare the performance of the proposed antenna with the help of full-wave electromagnetic simulation software called CST Microwave Studio. The proposed curved antenna was fabricated, and a PNA network analyzer was used to measure the S11 of the proposed antenna. It was demonstrated that the measured S11 covers the desired frequency range.

“…The latter drawbacks could be successfully addressed and overcome by novel additive manufacturing (AM) methods including polymer-based 3D printing, such as digital light processing (DLP) [11] or stereolithography (SLA) [12], and a subsequent metallization process. By making use of the slotted waveguide approach, where non-radiating slots are introduced into the narrow walls of the waveguide, printing and metallization qualities can be enhanced, enabling the fabrication of even relatively complex structures for millimeterwave (mmWave) frequency range, such as waveguides, or waveguide paths for E- [13,14] and D-band [15], hybrid couplers for both bands [16][17][18], W-band SWAs [19], helix antennae for 77 GHz [20] that can be used in imaging applications [21], wavemode transitions [22,23] and even entire six-ports from one monolithic model [24].…”

Additive Manufactured Waveguide for E-Band Using Ceramic Materials

Ceramic materials are chemical- and temperature-resistant and, therefore, enable novel application fields ranging from automotive to aerospace. With this in mind, this contribution focuses on developing an additive manufacturing approach for 3D-printed waveguides made of ceramic materials. In particular, a special design approach for ceramic waveguides, which introduces non-radiating slots into the waveguides sidewalls, and a customized metallization process, are presented. The developed process allows for using conventional stereolithographic desktop-grade 3D-printers. The proposed approach has, therefore, benefits such as low-cost fabrication, moderate handling effort and independence of the concrete waveguide geometry. The performance of a manufactured ceramic WR12 waveguide is compared to a commercial waveguide and a conventionally printed counterpart. For that reason, relevant properties, such as surface roughness and waveguide geometry, are characterized. Parsing the electrical measurements, the ceramic waveguide specimen features an attenuation coefficient of 30–60 dB/m within the E-Band. The measured attenuation coefficient is 200% and 300% higher compared to the epoxy resin and the commercial waveguide and is attributed to the increased surface roughness of the ceramic substrate.
