“…The demand for directional antennas has continuously increased, and at the same time, the design approaches have also been constantly innovated. For instance, a compact dualfrequency directional antenna for the application of RFID readers has been proposed in [31]. Additionally, to obtain a high gain, a large slot antenna array has been designed [32].…”

5G mmWave broadcasting is considered to be the main method of future broadcasting. However, the mmWave transmission has a large space loss, especially in tunnels. In order to compensate for the attenuation of the broadcast signal, a directional horn antenna is designed in this paper. Substrate integrated waveguide (SIW) technology, dual-element arrays and extension structures are used to improve the antenna structure and achieve good directional characteristics. The multi-objective genetic algorithm (MOGA) is used to optimize the antenna parameters and improve optimization efficiency. Ultimately, the whole antenna was 28.2 mm in length and 28.6 mm in width, and the FR4 material, with a relative permittivity of 4.4, was used as a dielectric plate. The maximum gain of the antenna is 8.06 dB, and the bandwidth with gain greater than 6.5 dB is nearly 2 GHz. Antenna performance simulation and test results show that the extended semicircular structure is beneficial in enhancing the directional radiation of the antenna. This provides a reference method for directional antennas applied to 5G millimeter wave bands to increase gain and narrow beams.

“…One of the basic techniques to implement a multi-band antenna is integrating multiple resonating elements, modifying radiating patch and ground plane in a microstrip patch antenna. In [3,4], a dipole with two different arm lengths, using a shorting pin between ground and patch [5,6], and parasitic elements in laptop application [7] result in two resonating frequency bands. Triple and quadband [8,9] patch antennae are discussed using trapezoidal and crinkle fractal shapes.…”

A novel planer, compact and quarter-wave transformer-coupled fed multi-band antenna is proposed and designed. The antenna uses a split-ring resonator (SRR) inspired ring metamaterial unit cell. The proposed ring metamaterial unit cell gives single negative (Epsilon negative) behaviour, which improves antenna performance. A partial ground and a quarter-wave transformer-coupled feed line are used to improve the impedance matching of the antenna. The antenna gives multi-band operation at resonating frequencies, 3.5, 8.5, and 13.7 GHz, with 2.9-4.5 GHz, 8.0-10.34 GHz, and 12.3-14.3 GHz, respectively. The maximum gains at resonating frequencies are 1.5 dBi, 4.1 dBi, and 6.5 dBi, with good impedance matching. The novelty of the antenna design is that the loading of the ring unit cell gives resonance at a much smaller wavelength than the resonant wavelength. The proposed antenna provides a miniaturized and multiband response compared to a conventional patch antenna.

“…[9] looked into the possibility of improving antenna performance using a metamaterial-inspired antenna made up of one or more unit cells. Metamaterial-inspired antennas have been used to study impedance matching, bandwidth enhancement, gain improvement, compactness, and multiband antenna design [10][11][12][13][14][15].…”

The purpose of this study is to design a multiband antenna using metamaterial for efficient satellite communication. The majority of the antennae described in the available research suffer from a variety of limitations, including intricate designs, great footprints, and erratic radiation patterns. Therefore, there is a significant demand for antennae that are of a smaller size but nevertheless perform well. This paper proposes a quad-band stub-incorporated split octagonal ring antenna for satellite communication-dependent wireless applications. The suggested antenna is built on an FR4 substrate that measures 22 × 39 × 1.6 mm 3 . CST EM studio software is used for the entire simulation. The proposed antenna resonates at four different bands, with operating frequencies ranging from 2.15 GHz to 2.30 GHz, 2.86 GHz to 3.76 GHz (due to stub 1), 4.47 GHz to 5.24 GHz (due to stub 2), and 5.67 GHz to 6.35 GHz (due to stub 3). (due to gap between the stub). The proposed antenna has resonant frequencies of 2.23 GHz, 3.28 GHz, 4.77 GHz, and 5.89 GHz, and bandwidths of 153 MHz, 9011 MHz, 7692 MHz, and 6813 MHz. Parametric analysis is used to select the best values. The designed antenna is built and tested. The measured and simulated values for return loss, gain, E-plane, and H-plane are compared, and they agree. Its dual-band operation, compact size, steady radiation pattern, and gain above 1 dBi across the whole resonating band make it suited for ISM, WIFI, WLAN, WIMAX, 5G, and C band satellite applications.
