A Frequency-Selective Surface (FSS) is any thin, repetitive metal surface designed to reflect, transmit, or absorb electromagnetic radiation according on the frequency of the wave. The entering plane wave will either be transmitted (passband) or reflected back (stopband) depending on the characteristics of the unit cell. This happens when the frequency of an electromagnetic (EM) wave coincides with the resonance frequency of the FSS components. As a result, an FSS is a spatial filter capable of allowing or inhibiting EM waves of a certain frequency range in free space. FSSs have now been widely investigated, and great progress is being made in the field of their design and implementation for a wide range of practical applications, from microwave to optical frequencies. The Frequency Selective Surface attached to the new center-fed circular patch antenna is presented. A wide band from 5 GHz to 6.2 GHz is achieved with a monopole-like radiation pattern. According to simulation results of the proposed antenna structure, it can be applied in ISM band applications, wireless audio and video systems and other wireless communications at 5.8 GHz. It has a simulated maximum gain of 5.36 dBi and a bandwidth of 31.1 %. Throughout the operational band, the omnidirectional radiation pattern is fairly constant. The overall dimensions of the antenna are 27.34 27.34 mm 2 including FSS structure thus makes a compactable wideband system at 5.8 GHz. A circular patch antenna with diamond slot at center initialize first resonance at 5.8 GHz with a dimension of 20 20 mm 2 and performance parameter is further improved by appending FSS Structure.

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.
