The two-port antenna is designed for THz communication where isolation achieved with the defective ground. radiator of inspired by half-cutting technology which reduces size and makes it a compact antenna. T-shaped stub open-ended slot are used to modify capacitive inductive reactance diminish discontinued surface current improve port isolation. improves electric length ground enhances up 3.4 dB in weaken mutual create non-uniform intensifications 7.7 at 2.2 THz. dimensions design 100 µm x 105 edge distance antennas only 0.20λ maximum 30 bandwidth 1.74 2.52 that can be applicable wireless applications.
