This paper presents a novel compact circular shaped fractal monopole patch antenna (FMPA) with de-fected ground structure (DGS). The suggested fractal geometry has been created by using an iterated function system (IFS). The primary aim behind the inclusion of this fractal geometry is used to achieve miniaturization and wideband performance. The complete geometry of the prescribed FMPA for 5G applications is constructed by incorporating fractals with square and star with eight segments; in each segment we create a square with a rotation of 45° from one segment to another. The dimension of proposed fractal geometry is 14 6 mm 2 . The bottom plane of the antenna consists of defected ground structures (DGS) to acquire better isolation and miniaturization. The proposed structure provides a good performance metrics such as gain, and reflection coefficient. The substrate used in this work is Rogers RO4003C, which has a dielectric constant of 3.55, a high of 0.2 mm, and loss tangent of 0.025. Computer Simulation Technology-Microwave Studio (CST) is used to evaluate this antenna. The suggested antenna operates at 26 GHz with an impedance bandwidth of 0.357 GHz along with maximum reflection coefficient of – 24.426 dB. The prescribed antenna attains a peak gain of 3.83 dB, maximum radiation efficiency of 95.78 % and desired radiation patterns by maintaining its compact size.

Terahertz band gap is the range of frequency lying between the microwave band and the optical band, its range spectrum starts from 0.1 THz to 10 THz. This band provides unallocated wide bandwidth as well as very high-speed communication in the futuristic applications. This article presents a broadband microstrip 1 2 array antenna powered by hybrid coupler in terahertz band (around 2.45 THz). To reach this Broadband antenna, at first, a wideband 3 dB hybrid coupler is designed and optimized. After that, two basic elements of square shaped with slots are fed by the two output ports of the coupler. The results obtained reports that the suggested antenna offers – 10 dB wide bandwidth equals to 846 GHz (from 1.91 to 2.77 THz) with good impedance matching, maximum directivity equals to 8.86 dBi at the operating frequency 2.45 THz. Additionally, it offers the capability of beam steering which can be obtained by switching of the input ports of the coupler. Thus, the antenna can produce two beams at 30 . The structure and simulation results of the proposed antenna have been done on Rogers RT/duroid 5880 substrate. The total size of the proposed microstrip array antenna is 110 112 1.56 m 3 . Due to its capability of beam steering and broadband characteristic, the proposed antenna is a potential candidate for Terahertz band applications such as materials characterization in the THz band, medical imaging and future high-speed wireless communication.
