Additively manufacturing (AM) technology has been changing our daily lives. As one of the fundamental manufacturing methods in what is known as the industry 4.0 concept, AM technology is now a driving force for revolutionary manufacturing microwave components with high-performance, high-accuracy, low-cost, and short production cycles. The materials utilized in additive manufacturing have been developed from single-dielectric/metal-only materials to multi-material printing (dielectric and conductive materials), extending the possibility of AM-inspired designs from microwave to terahertz regime. An overview from single-material to multi-material AM printing systems and their applications in microwave, millimetre-wave and terahertz designs are presented.
This project focuses on designing some millimetre-wave antennas for 5G applications based on 3D printing technology. In this research, electrical characteristics of the dielectric materials used by the 3D printing machine, including its dielectric constant and loss tangent, are investigated, and measured. Taking advantage of the AM technology, multi-layer devices including transmission lines, antennas, bandpass filters, couplers and reflect arrays, which perform well and have compact sizes, are proposed and fabricated for 5G applications. The main contents are as follows:
Chapter 1: Introduction about the details of multi-material integrated additive manufactured electronics (AME) solution, which plays an essential role in the fabrication of the designs.
Chapter 2. Literature review- from single-material to multi-material additively manufacturing technology. This chapter introduces the development history of 3D printing technique. Relevant content has been published in the journal of IEEE Microwave Magazine.
Chapter 3. 3D-printed low-profile single-substrate multi-metal layer devices with compact size. This chapter demonstrates a 3D-printed low-profile single-substrate multi-metal layer antennas and array with ultralow profile and broad operational band. Related content has been published in the journal of IEEE Access.
Chapter 4. 3D-printed compact transmission lines, and multi-layer bandpass filters. This chapter proposed a compact additively manufactured bandpass filter (BPF) with good out of band rejection. Related content has been published in IEEE Transactions on Electron Devices. Next, a novel compact vertically integrated multi-layer composite right/left-handed (CRLH) BPF with low loss and wide operational band is proposed. Related content is being submitted to the journal of IEEE Transactions on Microwave Theory and Techniques.
Chapter 5. 3D-printed metasurfaces for independent manipulation of broadband orbital angular momentum. This chapter demonstrates an 3D-printed metasurface generating orbital angular momentum (OAM) states with different topological charges at two operational broadbands for high-information capacity and high-security applications. Related content has been submitted to the journal of Additive Manufacturing.
