Optimization of antenna parameters is important for achieving the best design that has higher results for gain and bandwidth while also having a smaller size. One such antenna design is numerically investigated and presented in this research. The antenna is optimized to an O-shape fractal design from a square patch design. The antenna is created by etching a slot of a square patch and making an O-shape fractal metamaterial patch antenna that operates on the THz band. The THz patch antenna is also investigated for its metamaterial properties. The optimization of the THz patch antenna is carried out for substrate height, slot length, and slot width. The optimized design has a size of 65 × 65 µm2. The highest bandwidth of 31.4 THz (138%) and the highest gain of 11.1 dBi is achieved. The optimized design is then investigated for multiple elements. The two-element MIMO antenna design using an O-shape patch is investigated to observe its performance and compare it with an O-shape single-element design. The two-element MIMO antenna design gives two bands with a bandwidth of 18 THz (113%) and 21 THz (56%). The gain of this design is 5.18 dBi and the size is 130 × 65 µm2. A comparison between the O-shape single-element fractal design, two-element fractal MIMO design, and other published designs is carried out. The compact, broadband, and high gain design presented can be used for 6G high-speed mobile communication devices.

“…A four-port antenna with a dimension of 45µm×45µm generates a bandwidth range of 2.38 -11.18 THz and utilizes a self-similar elliptic structure with a polyamide substrate [26]. A tunable-enhanced isolation MIMO antenna is reported [27], which provides a bandwidth range of 5.68 -6.51THz and achieves ECC = 4.818×10 -7 . A frequency span of 1.0 -20.0 THz in a twoport antenna provides maximum isolation of 38dB with S 11 = -50.85dB [28].…”

A Novel Conformal Quasi-Yagi Antenna With Offset Feed for High Directional 300GHz Applications

et al. 2023

This communication reports a conformal offset feed Quasi-Yagi antenna at 300 GHz for high-directional applications. A novel offset feed mechanism is adopted to obtain directional behavior from a conventional planar structure. The proposed antenna is designed on a Silicon-dioxide (SiO 2 ) dielectric substrate having a permittivity (ε r ) of 4 and a height of 60μm. A gold material of thickness 5µm is used as a conducting metal in the top and bottom layers. This antenna consists of an offset feed patch, partial ground as a reflector, and three director elements forming a Quasi-Yagi antenna. This conformal structure operates from 270 GHz to 333 GHz and provides a peak gain of 8.62dBi at 300 GHz in the end-fire direction. An analysis of different metals and parametric variation in metal thickness, substrate thickness, patch length, and width is also reported for a better understanding of the evolution of the proposed structure. A lumped equivalent circuit is also developed for the proposed structure to study its transmission line model. A good agreement is also noted between the EM simulation (HFSS, CST) and circuit simulation (ADS).
