| Summary: | In this paper microstrip ring antenna is designed for triple, quad, and super wideband terahertz application. Three antenna configurations are discussed here with application in upcoming 6G technology, Health monitoring systems, wireless sensor network, and the Internet of Things (IoT). A square ring resonator antenna designed on 710 × 910 × 10 µm3 Rogers R03003 substrate. The first antenna is working on 374, 444, and 510 GHz with maximum bandwidth of 40 GHz. Further ground structure of ring antenna defected for super wide bandwidth of 192 GHz. Third antennas show quad-band performance with fractal rings. The result and performance indicate that the recommended antenna will be well-suited with compact future wireless devices. An soft High Frequency Structure Simulator (HFSS) is used for all simulation work.
