Flexible or wearable antennas are noticing exponential rise in demand for 5G technologies, wireless sensor network, the Internet of Things (IoT) system and health monitoring. This paper focuses on the study of different substrates in the development of a compact, flexible and robust antenna. In this paper, an octagonal ring resonator antenna has been designed for tri-band terahertz application. The antenna is working on triple band characteristics at 140 GHz, 340 GHz and 396 GHz with overall dimensions of 700 x 900 x 10 µm3. Three substrate materials Rogers R03003, polyamide and polyester are chosen for de-termining flexibility, durability as well as optimal antenna performance. The result and performance show that the recommended antenna will be compatible with compact flexible wireless devices. All simulation work has been done using electromagnetic software Ansoft High Frequency Structure Simulator (HFSS). The electromagnetic features like S11 parameters, VSWR, gain, efficiency and the radiation characteristics of such antenna are also explored.
