Compact and Low-Cost 3-D Printed Antennas Metalized Using Spray-Coating Technology for 5G mm-Wave Communication Systems

Abstract

Abstract-This paper presents a design of two compact, light, rigid and low-cost 3D-printed millimeter-wave antennas for 5G communication system. The proposed antennas consist of a radiating slot that is surrounded by a rectangular cavity and corrugations which boost the gain performance of the antennas. Furthermore, the proposed antennas are fabricated using 3Dprinting technology and they are metallized using novel, simple and low cost techniques which utilizes commercial conducive spray-coating technology. The proposed antennas operate at 28-GHz band, where the first design is fed by a waveguide to prove the performance, while the second design is fed by a microstrip line to demonstrate the ability to be integrated into a compact structure. Measurement results show a wide impedance bandwidth which enables the proposed antenna design to be a strong candidate for 5G applications.

Additively manufactured trapezoidal grooves for wideband and high gain Ku‐band antenna

“…The antenna is assumed to be fed from WR‐75 waveguide. Slot‐coupled, cavity antenna was also proposed in Reference but there are two major differences between the proposed antenna and Reference : first cavity is wider, hence lower cut‐off frequency than the feed waveguide, and the groove shape is totally different. With these distinct features, proposed antenna gain is improved substantially over existing designs.…”

Compact K/Ka‐band dipole antenna element with ball grid array packaging

“…Hardware integration and cost are challenges for millimeter wave antennas 1‐3 . In recent years, several millimeter wave antenna elements and antenna arrays have been extensively studied 4‐13 . According to the radiation patterns, the millimeter wave antennas can be divided into two types.…”

“…One is the endfire antennas, 4‐6 such as the quasi‐yagi antenna array with modified folded driver, 4 the magnetoelectric dipole antenna array, 5,7 and the printed‐dipole antenna array in Reference 6. The other is the broadside antennas in References 7‐12. For example, the magnetoelectric dipole leaky‐wave antenna in Reference 7, the 3D printed antenna in References 8 and 9, and the tilted combined beam antenna in Reference 10.…”

“…The other is the broadside antennas in References 7‐12. For example, the magnetoelectric dipole leaky‐wave antenna in Reference 7, the 3D printed antenna in References 8 and 9, and the tilted combined beam antenna in Reference 10. However, the antennas in References 7‐10, are fed by the waveguide, and the antennas in References 11 and 12 are fed by the coaxial line.…”

Design and Performance Comparison of Rotated Y-Shaped Antenna Using Different Metamaterial Surfaces for 5G Mobile Devices

“…As lower frequency bands are highly congested [Khan, Sehrai and Ali (2019)], and unable to provide higher bandwidth and data rate. Thus, one solution to this problem is to move towards the higher frequencies in the spectrum to achieve higher bandwidth and data rate requirements [Jilani, Abbas, Esselle et al (2015); Alkaraki, Andy, Gao et al (2018)]. The future Fifth Generation (5G) communication is mostly focused on the millimeter wave spectrum (30-300 GHz) ; Khan, Rehman, Ahmad et al (2015); Hong, Baek and Ko (2017)] and is expected to provide 100-1000 times higher data rate as compared to the existing networks [Goudos, Tsiflikiotis, Babas et al (2017); Khan, Rehman, Ahmad et al (2015); Muirhead, Imran and Arshad (2016); Li, Sim, Luo et al (2017)].…”
