In this work, a fully 3D-printed choke corrugated Gaussian profile horn antenna (GPHA) using high-conductive filaments and a low-cost modular 3D-printing technique is implemented. The choke corrugated GPHA operates in the Ka-band, with a central frequency of 28 GHz. Although the antenna can be printed in one piece as its dimensions are within the printing limits, four pieces compose the three sections of the final 3D-printed antenna. The numerical simulations and measurements of the antenna show a good agreement, validating the possibility of cost-effective modular fabrication of this complex type of antennas.

Substrate integrated waveguides (SIW) technology is employed to design a uniform long slot leaky-wave antenna (LWA) in millimeter-wave (mmWave) band. The structure is then loaded by a 3D printed sinusoidal periodic pattern of Photopolymer VeroClear dielectric. This makes a periodic LWA which means that it is possible to regulate a desired higher order space harmonic to form the beam and to tilt it to the direction of interest. To showcase the practicality of method, the dielectric pattern is designed in such a way that the beam is tilted to the backward-quadrant at θm = −15 • at f = 35 GHz. The structure is fabricated and the S-parameters are measured which shows a good agreement with the simulated results.

“…Furthermore, low metal-polymer adhesion is another limitation of using a polymer as a flexible substrate for conformal antennas in biomedical applications [8]. This poor metal-polymer adhesion causes the detachment of the conductive layer from the substrate under tough mechanical conditions.…”

In this paper, low-cost mold silicone and silicone elastomers are investigated as substrates for the realization of flexible antennas. A methodical dielectric characterization is carried out, followed by a detailed explanation of the manufacturing process of the silicone elastomers. The prepared silicone elastomer substrates are also subjected to mechanical tests to ensure flexibility and robustness. The mechanical tests corroborated the utilization of the prepared silicone elastomers for the flexible antennas. Silicone has limited adhesion to metal, so when producing a silicone substrate, a 0.5 mm deep cavity is created with a negative impression of the intended metal component. Consequently, the metal layer is embedded within the silicon substrate, aligning the top surface of the metal flush with the silicone substrate edges. The radio frequency (RF) structure incorporates ridges within the silicone substrate to form a gap, effectively securing the metal on the surface of the silicone. Finally, to prevent the metal from falling from the silicone substrate, Kapton tape is laminated on the substrate. The wrapping of the Kapton tape additionally provides protection from moisture since the silicone elastomer substrate is prone to moisture absorption. The proposed technique is experimentally verified by designing and prototyping a coplanar patch antenna using copper and conductive woven fiber on the silicone substrate. The simulation analysis and experimentation results authenticated the effectiveness of the proposed technique to design a flexible antenna on the silicone elastomer substrates. It is also concluded that the conductive woven fiber-based prototype offers higher flexibility as compared to the copper-based prototype. It is also clinched that there exists a trade-off in flexibility and performance characteristics due to the conductivity and texture difference between the copper and conductive woven fiber.
