“…Table 2 gives a comparison of various parameters of the designed antenna and other similar antennas. The comparison shows that the proposed antenna configuration has several advantages over previously reported antennas [8][9][10][11][12][13][14][15][16][17][18][19][20][21], in terms of bandwidth ratio, compact size, number of radiating patches, and isolation among radiating elements. Further, the usage of CPW feeding in the proposed antenna provides the advantage of easy integration into portable devices.…”

“…In [19], the authors presented a UWB MIMO antenna with two QSC half-circular monopoles, where the notch band and isolation were obtained by introducing parasitic strips of Levy's and Hilbert fractal-shaped strips, respectively. A dual-port SWB MIMO antenna composed of two circular patches, asymmetrical E-shaped stubs, and mushroom-shaped electromagnetic band-gap (EBG) structures was suggested in [20]. In [21], a four-port SWB MIMO antenna with QSC resonating elements and exhibiting WLAN and Wi-MAX bands elimination characteristics was proposed.…”

A compact, low-profile, coplanar waveguide (CPW)-fed quad-port multiple-input–multiple-output (MIMO)/diversity antenna with triple band-notched (Wi-MAX, WLAN, and X-band) characteristics is proposed for super-wideband (SWB) applications. The proposed design contains four similar truncated–semi-elliptical–self-complementary (TSESC) radiating patches, which are excited through tapered CPW feed lines. A complementary slot matching the radiating patch is introduced in the ground plane of the truncated semi-elliptical antenna element to obtain SWB. The designed MIMO/diversity antenna displays a bandwidth ratio of 31:1 and impedance bandwidth (|S11| ≤ − 10 dB) of 1.3–40 GHz. In addition, a complementary split-ring resonator (CSRR) is implanted in the resonating patch to eliminate WLAN (5.5 GHz) and X-band (8.5 GHz) signals from SWB. Further, an L-shaped slit is used to remove Wi-MAX (3.5 GHz) band interferences. The MIMO antenna prototype is fabricated, and a good agreement is achieved between the simulated and experimental outcomes.

The intensive research in the fifth generation (5G) technology is a clear indication of technological revolution to meet the ever-increasing demand and needs for high speed communication as well as Internet of Thing (IoT) based applications. The timely upgradation in 5G technology standards is released by third generation partnership project (3GPP) which enables the researchers to refine the research objectives and contribute towards the development. The 5G technology will be supported by not only smartphones but also different IoT devices to provide different services like smart building, smart city, and many more which will require a 5G antenna with low latency, low path loss, and stable radiation pattern. This paper provides a comprehensive study of different antenna designs considering various 5G antenna design aspects like compactness, efficiency, isolation, etc. This review paper elaborates the state-of-the-art research on the different types of antennas with their performance enhancement techniques for 5G technology in recent years. Also, this paper precisely covers 5G specifications and categorization of antennas followed by a comparative analysis of different antenna designs. Till now, many 5G antenna designs have been proposed by the different researchers, but an exhaustive review of different types of 5G antenna with their performance enhancement method is not yet done. So, in this paper, we have attempted to explore the different types of 5G antenna designs, their performance enhancement techniques, comparison, and future breakthroughs in a holistic way.

A compact size, coplanar waveguide (CPW) fed two-antenna multiple input multiple output (MIMO) with high isolation and excellent impedance matching operating in n77/n78/n79 5G NR sub-6 GHz/Wi-Fi-5/V2X/DSRC/ Wi-Fi-6/INSAT-C is proposed for future wireless applications. Each antenna element is a CPW-fed antenna type composed of an "inverted-A," "y-shaped,"and "small extended stub" structures. The two-antennas are deployed in the same orientation at an edge-to-edge distance of 0.06λ (λ represents free-space wavelength at 3.70 GHz) on a shared rectangular substrate having designed footprint of 0.57λ × 0.39λ. To attain high isolation of greater than 20 dB in the desired bands of interest, a novel comb-shaped isolating structure is deployed between the two antenna elements. From the measured results, the proposed MIMO antenna has exhibited wide 10-dB impedance bandwidth of 88.57%(3.00-7.70 GHz), good gain above 3 dBi and efficiency larger than 78% throughout the desired operating bands. Moreover, the MIMO diversity performance metrics including envelope correlation coefficient (ECC), diversity gain (DG), mean effective gain (MEG), total active reflection coefficient (TARC), channel capacity and channel capacity loss (CCL) are also achieved.
