As the demand for high data rates is increasing day by day, fifth-generation (5G) becomes the leading-edge technology in wireless communications. The main objectives of the 5G communication system are to enhance the data rates (up to 20 Gbps) and capacity, ultra-low latency (1 ms), high reliability, great flexibility, and enhance device to device communication. The mentioned objectives lead to the hunting of the millimeter-wave frequency range which lies from 30 to 300 GHz for 5G wireless communications. To design such high capacity, low latency, and flexible systems, antenna design is one of the crucial parts. In this paper, a survey is presented on various antenna designs with their fabrication on different types of substrates such as Rogers RT/duroid 5880, Rogers RO4003C, Taconic TLY-5, etc., at different 5G frequency bands. The different configurations of antennas that covered antenna arrays, multiple-input multiple-output (MIMO) antennas, phased antennas, and beamforming antennas are discussed in detail with their applications. The design of MIMO antennas in the 5G frequency band occupied less space so mutual coupling reduction techniques are required for maintaining the required gain, efficiency, and isolation. This paper is also focused on the mutual coupling reduction techniques and diversity in MIMO antennas.

“…Electromagnetic bandgap (EBG) as a periodic 2D element is gaining a lot of interest for passive microwave circuit and antenna design due to their attractive interaction with electromagnetic (EM) waves [1]. EBG is broadly classified as mushroom [2] and uniplanar type [3], which exhibits properties such as surface wave suppression within its frequency bandgap and in-phase reflection for plane wave incidence.…”

This paper presents a broadband miniaturized Fabry–Perot cavity resonator antenna (CRA) made of novel electromagnetic bandgap (EBG) superstrate as partially reflecting surface (PRS) and reactive impedance surface (RIS) backed rectangular patch antenna. To the best of the authors' knowledge, the proposed EBG exhibits the highest stopband bandwidth (BW) with a bandgap existing between 7.37 and 12.4 GHz (50.9%). Frequency-selective property of the EBG is utilized under plane wave incidence to demonstrate it as PRS superstrate in CRA antenna. The cavity is excited with a rectangular microstrip antenna which is made of two dielectric substrates with an additional RIS layer sandwiched between them. The RIS provides wideband impedance matching of the primary feed antenna. A 7 × 7 array of the EBG superstrate is loaded over the patch antenna having an overall lateral dimension of only 45 × 45 mm2 or 1.62 λ0 × 1.62 λ0 where λ0 is the free space wavelength at the center frequency of 10.8 GHz. The proposed Fabry–Perot CRA (FP-CRA) achieves gain enhancement of 6.59 dB as compared with the reference antenna and has a 10 dB return loss BW of 23.79% from 10.07 to 12.79 GHz. A prototype of the FP-CRA is fabricated and experimentally tested with single and dual layers of EBG superstrate. Measured results show BWs of 21.5 and 24.8% for the two cases with peak realized gain of 12.05 and 14.3 dBi, respectively. Later a four-element antenna array with corporate feeding is designed as the primary feed of the CRA. The simulation result shows a flat gain of >13 dBi with gain variation <1.2 dB over the impedance BW of 13.2%.

“…A novel design of a uniplanar compact electromagnetic bandgap (EBG) for millimeter-wave wearable antennas is presented. The unit cell of the EBG has a flexible fractal design, which is easily fabricated at millimeter-scale [15][16][17]. The technology to design and develop the printed antennas has been continuously altered from the structural view of configuration to antenna features improvement.…”

A miniaturized wearable antenna with a compact EBG with checkerboard structure is designed. The structure is placed on a denim jeans material with thickness of 0.7mmand having dielectric constant of 1.7 and a loss tangent of 0.02. The antenna operates at a frequency of 2.5 GHz and has 0.33GHz bandwidth and 13.2% impedance bandwidth for ISM band applications. The prototype is robust as well as compact and adheres to the wearable applications. The EBG is used to improve the gain and reduces the Specific Absorption Rate (SAR) which is an essential in wearable applications. The gain of 6.5dBi and SAR of 0.0312W/Kg is achieved, satisfying the required conditions of the antenna in the presence and absence of EBG to assess the changes caused in the performance of the antenna due to the insertion of EBG.
