Abstract

This paper presents a compact microstrip-based dual-band antenna for terahertz (THz) technology, catering to the increasing demand for high-frequency, high-gain, and wideband THz antennas. THz technology has numerous applications, including its demands in bioinformatics and healthcare. To address this need, the proposed antenna operates in two frequency bands: 3.6 THz to 4.3 THz and 5 THz to 5.7 THz, enabling its use in THz band communication. The antenna design features a microstrip patch with two transverse slots and one longitudinal slot as a radiator, fed with a microstrip line. The transverse slots enable dual-band resonance, while the longitudinal slots enhance bandwidth and efficiency. Using a 10µm thick polyamide material with a dielectric constant of 3.55, the antenna achieves a compact size of 40 × 40 µm2, lightweight construction, high radiation efficiency, and a wide impedance bandwidth. Simulation results confirm good impedance matching characteristics, with minimal voltage standing wave ratio and return loss of -10dB or less. The antenna exhibits an impedance bandwidth of -10dB at 700 GHz, a peak radiation efficiency of 85%, a peak gain of 7.86 dB, and an omnidirectional radiation pattern. These favorable attributes position the proposed antenna as an excellent choice for various THz applications, particularly in bioinformatics and healthcare applications.
