Compact and Low-Cost 3-D Printed Antennas Metalized Using Spray-Coating Technology for 5G mm-Wave Communication Systems
Shaker Alkaraki,Andre Sarker Andy,Yue Gao,Kin-Fai Tong,Zhinong Ying,Robert S. Donnan,Clive Parini +6 more
TL;DR: In this paper, a design of two compact, light, rigid, and low-cost 3-D printed millimeter-wave antennas for a 5G communication system is presented, where the proposed antennas consist of a radiating slot that is surrounded by a rectangular cavity and corrugations.
Journal ArticleDOI
Radiation Energy and Mutual Coupling Evaluation for Multimode MIMO Antenna Based on the Theory of Characteristic Mode
TL;DR: In this article, the authors presented a novel method to evaluate radiation energy and mutual coupling in multimode antennas based on the theory of characteristics mode, how much each mode occupies the radiation and the mutual coupling from each feeding port is calculated with the modal energy occupied coefficients.
Journal ArticleDOI
Performance Comparison of Simple and Low Cost Metallization Techniques for 3D Printed Antennas at 10 GHz and 30 GHz
TL;DR: Simulation and measurement results show that the proposed techniques have a reasonable performance in both bands which qualifies them to be simple and low cost possible alternative of the electro-less plating for some antenna applications.
Design of microstrip patch antenna using slotted partial ground and addition of stairs and stubs for UWB application
TL;DR: In this paper, a simple narrowband patch antenna is designed before proceeding to the optimum geometry of UWB antenna and a special configuration of patch antenna with slotted partial ground and addition of stairs and stubs was designed and optimized using CST Microwave Studio (CSTMWS).
Journal ArticleDOI
mm-Wave Low-Cost 3D Printed MIMO Antennas With Beam Switching Capabilities for 5G Communication Systems
Shaker Alkaraki,Yue Gao +1 more
TL;DR: This paper presents designs and prototypes of low cost multiple input multiple output (MIMO) antennas for 5G and millimetre-wave (mm-wave) applications that are fabricated using 3D printing and are able deliver beams in multiple directions that provide continuous and real time coverage in the elevation without using phase shifters.
