Considering the potential for future scalability, the ultimate objective of this thesis is to develop a novel additive technique for producing antennas on flexible substrates (Polyimide -PI or Liquid Crystal polymer - LCP). This approach aims to move away from the traditional subtractive methods commonly used in Flexible Printed Circuits (FPCs).Central to this approach is the sustainable use of copper sulfate waste from the semiconductor industry, repurposing it for high-value production in the flexible printed circuit market. This thesis presents a pioneering approach in antenna manufacturing using an innovative additive technique for depositing copper on aluminum electrodes through chemical replacement or galvanic displacement, a significant breakthrough for applications in RFID and automotive radar systems. Central to this study is the exploration of chemical replacement as a crucial aspect of additive technology in advancing antenna design. Initial chapters lay the theoretical groundwork and describe the experimental methodology, setting the stage for practical applications.
In the first part of this study, this technique is adeptly applied to the fabrication of RFID tag antennas on PET flexible substrates, achieving impressive electrical properties and operational efficiency, highlighted by a notable return loss S11 of -22 dB at 1.93 GHz.
In the second part of this thesis, extends the application to 24GHz array patch antennas for radar systems, employing an eco-friendly additive process on LCP substrates. This method achieved low resistivity and a promising gain of 8.34dBi, validating its effectiveness in high-frequency applications.
In the third part of this thesis ,explores various electroplating solutions for copper deposition in CPW designs, culminating in the development of a precise 50-micron CPW on a 0.025 µm LCP substrate and a corner-truncated phase array antenna design optimized for 77GHz~82GHz radar applications, demonstrating significant advancements in antenna performance. This approach, represents circular economic principles, aims to significantly benefit the industry. Additionally, the research introduces a groundbreaking additive technique in antenna manufacturing, which could establish new standards, encourage innovations and advancements in RFID and radar technology applications.
