Abstract
The demand of flexible antennas for the seemingly endless market of wearable sensing systems, wireless devices, Internet of Things (IoT) framework, and 5G technology, to name a few, has been exponentially growing. Designing antennas to meet this demand depends on factors such as antenna types, substrate materials, conductive materials, material properties, feeding techniques, fabrication methods, and antenna performance. The aim is to develop high performance flexible antennas that have high signaling strength, high speed, high gain, wide operating bandwidth, compacted size, etc., and maintain high performance under bending conditions. The aim of this research is twofold. Firstly, it explores three different flexible microstrip antennas fabricated with cost effective fabrication methods such as inkjet printing with silver nanoparticles ink and milling copper cladded substrate. The first antenna was inkjet printed on PET substrate operating in the ultrawideband (UWB) frequency domain from 3.04-10.70 GHz, and 15.18-18 GHz (partial Ku band) targeting IoT and wearable devices and applications. The second antenna has miniaturized dimensions of 10 x 6 x 0.135 mm3, which was fabricated using inkjet printing on PET as well. It has an ultrawide-high-frequency-band operating from 10.50 to 31.75 GHz covering the upper X, Ku, K, and the lower Ka bands targeting 5G technology and communication devices for mobile networks. The third antenna, with dimensions of 10 x 10 x 0.787 mm3, was fabricated with a LPKF (Leiterplatten-Kopierfräsen) milling machine using Rogers RT5880 which is a flexible copper cladded substrate. This antenna operates under a superwideband frequency range from 10-110 GHz targeting the Millimeter Wave (mmW) spectrum. The second fold of this thesis reviews high temperature microstrip antennas and sensors and their applications, and the need for materials that can withstand severe conditions without altering performance.
