“…There is an increasingly strong interest in 3D printing technology for cheap and fast antenna manufacturing using fused deposition modeling (FDM) and direct metal laser sintering (DMLS). [33][34][35][36][37][38][39][40][41][42][43][44][45] As it has been mentioned before, it is aimed to introduce a high performance, easy to prototype and low cost antenna design using 3D printing technology. In Figure 10 3D prototyped antenna and FSS structures have been given where all the design structure have been printed and then some parts have been coated with copper.…”

One frequently addressed technique for the performance enhancement of radiating elements in the form of microstrip antennas is the utilization of dielectric resonators. A dielectric resonator antenna (DRA) has a conventional structural formation similar to any microstrip patch antenna where, at least, one additional dielectric layer has been placed over the radiating element. In this paper, it is aimed to propose a high performance, easy to prototype, light weight, and low cost DRA in combination with frequency selective surfaces (FSS) for ISM band applications using 3D printing technology. The proposed 3D printed FSS loaded DRA has a measured gain of 5.6 dBi with S11 level less than −10 dB in the operation band between 1.98 and 2.68 GHz. Furthermore, the measured performance of 3D printed antenna is compared with the counterpart alternative antenna designs in the literature for the similar application fields. The novel FSS loaded DRA is not only much smaller than the counterpart antenna designs but also has a moderate gain characteristics which makes the proposed antenna design an optimal RF solution for ISM band wireless communication applications.

“…Kriging is a well-known interpolation technique, which is used in the deterministic simulation. Let us assume that variability analysis will be performed by changing d physical and geometrical parameters of the microwave device and that properties of this device are represented by a scattering matrix S. 1 The black-box model of this device can be built using K training samples. i th training sample (x i , y i ) is a pair of an input vector x i and output vector y i .…”

“…The rapid development of 3Dprinting technologies gives one great flexibility on device geometry but also is connected with limited accuracy of the manufacturing process. For example, Selective Laser Melting (SLM) technology can be used in 3D printing of RF components, while covering the wide range of materials that can be processed, including aluminum, titanium, and steel alloys the manufacturing accuracy range varies from 0.02 mm to 0.1 mm depending on the specific material used [1]. This variability is an unavoidable part of the manufacturing process and it leads to slight changes of the dimensions of the physical devices, which brings uncertainty of the response of the microwave components.…”

This paper presents a new approach for variability analysis of microwave devices with a high dimension of uncertain parameters. The proposed technique is based on modeling an approximation of system by its poles and residues using several modeling methods, including ordinary kriging, Adaptive Polynomial Chaos (APCE), and Support Vector Machine Regression (SVM). The computational cost is compared with the traditional Monte-Carlo method. To improve the efficiency, mesh deformation is applied within 3D FEM framework.

“…The antenna has been printed along the y-axis (each layer of polymer belongs to the ZX-plane), to favor good symmetry (both for ridges and slots) with respect to the ZY-plane regardless of SLA tolerances. Consequently, the OMT V-port is tilted of 30° to 3D-print a self-supported piece, as it was also done in [15]. Such an action improves drastically the accuracy of the prototype without affecting the OMT performance.…”

This article investigates the potential of additive manufacturing for the fabrication of complex antenna geometries with enhanced performance at K-band. Stereolithography is here used to 3D-print a novel topology of dual-polarized leaky-wave antenna that allows for the control of its aperture illumination both in phase and magnitude. The antenna consists of a modulated triple-ridge square waveguide perforated on its top wall with crossed slots of different sizes. An orthomodetransducer is integrated within the structure for dual-mode operation. Monolithic implementation of this compound threedimensional structure is only possible thanks to additive manufacturing. In addition, low weight and compactness are attained comparing to classical milling. The present proposal is validated through the manufacturing of a low sidelobe levels prototype suitable for intersatellite links. The corresponding measured results are in very good agreement with full-wave predictions.
