A triband EBG loaded microstrip fractal antenna for THz application.

Future wireless communication needs antennas with multifunctional operation. This paper focuses on Terahertz Antenna that could be easily integrated with micro and nano devices. In this paper, an octagonal shaped Microstrip Fractal Antenna loaded with the EBG structure is designed for tri-band terahertz application. Triple band characteristic achieved by fractal radiating patch is loaded with Electronic Band Gap (EBG). The antenna features total size of 700-900 μm2 and resonates on three bands at 0.948 THz, 0.984 THz, and 1.040 THz. The result and performance indicates that the recommended antenna will be suitable for compact wireless devices and Monolithic Microwave Integrated Circuit (MMIC). All simulation works have been completed using electromagnetic software Ansoft High-Frequency Structure Simulator (HFSS) and CST studio suite. The electromagnetic features like S11 parameters, VSWR, gain, efficiency, and radiation characteristics of the suggested antenna are also examined. The simulation results show that this antenna has 9 dB realized gain at a resonating frequency of 0.948 THz. [ABSTRACT FROM AUTHOR]
