This paper presents a 100 μm GaAs-based 0.45-0.50 THz on-chip antenna based on metasurface and substrate integrated waveguide (SIW) technologies to realize a high-performance antenna. The antenna design consists of 2×4 array of metallic patches with circular slot embedded in rectangular resonator segments in a horizontal arrangement. The resonator segments are separated from each other by a narrow channel to create a coplanar waveguide which is used to excite the structure. This antenna structure, which is constructed on GaAs substrate, reduces substrate loss and surface waves. In addition, the metasurface essentially enlarges the effective aperture area of the antenna to enhance the gain and radiation efficiency of the antenna. The dimensions of the metasurface on-chip antenna is 0.8×0.8×0.13 mm3. The antenna exhibits an average gain and efficiency of 6.9dBi and 61.82%, respectively, which makes it a promising candidate for packaging in terahertz components.
