Aim: To develop a flexible, wide-band antenna on a polyethylene terephthalate (PET) substrate using laser surface texturing for selective metallization, enhancing performance and adaptability in various applications.
Brief description: This project focuses on employing laser-induced surface activation to modify PET substrates, enabling precise copper plating for antenna fabrication. Optimal laser processing parameters were determined, achieving metal deposition resolutions with trace widths as narrow as 50 µm and gaps of 75 µm. A 10x20 cm fractal antenna was produced and tested, demonstrating significant gains at targeted frequencies.
Benefits: The laser surface texturing technique allows for the creation of flexible antennas with high precision and performance. The fabricated antenna exhibited a gain of approximately 40 dBi at 1800 MHz and 26 dBi at 2100 MHz, indicating its effectiveness for wide-band applications. This method offers a scalable and efficient approach to manufacturing flexible electronic components, with potential applications in telecommunications and wearable devices.
