“…So far a wide variety of antenna configurations has been proposed for 5G mmWave applications. The focus of most of the published works has been on (1) developing single-band antennas with improved impedance bandwidth using stacked patch [3] or U-slot configurations [4,5], (2) studying different dual-band antenna configurations at 28/38 GHz frequency bands such as slot rectangular patch [6], planar inverted-F antennas [7], substrate integrated waveguide antennas [8], printed slot [9], and (3) generating polarization diversity/reconfigurability e.g., in [10][11][12]. However, to the best of the authors' knowledge, there is no published work in which an application-specific design approach for the development of scalable, miniaturized, high gain and broadband antennas for 5G mmWave BST has been discussed.…”

In this paper, we present a systematic approach for the development of application-specific antennas for 5G millimeter-wave (mmWave) base stations. First, an in-depth analysis of 5G mmWave base stations considering the required antenna gain and antenna elements to address different equivalent isotropic radiated power requirements is presented. This is followed by an evaluation of the realistic impact of different factors, which affect mmWave communication, namely output power of power amplifiers, antenna gain, losses and weather condition (rain), on transmission ranges between base station and terminals, considering the link budget analysis for an Urban Macro cell with the Non-Line-of-Sight transmission, as an example. Finally, based on a comparative analysis of published dual-band dual-polarized 5G mmWave antennas, we propose a novel configuration of a dual-band dual-polarized antenna for 5G mmWave base station applications, which overcomes the limitations of conventional antennas in published literature. Our proposed antenna covers the specified 3GHz bandwidths in the 5G mmWave n257 and n260 bands and reaches approximately 6 and 6.7 dBi, respectively in these bands. Furthermore, it exhibits at least 20 dB isolation between the polarizations and has dimensions of 1.831.83 1.2 mm. We modeled, simulated, fabricated, measured and analyzed this new antenna configuration. Excellent correlation is obtained between measurement and simulation results.
