“…The d between the slots is calculated to be half the guided wavelength. As a result, the radiating slots would have a 180-degree phase shift [16,17]. The normalized conductance Gn equations, as shown in Equation ( 1), are used to calculate the offset x.…”

This research constructs a 26 GHz waveguide slot antenna with decent gain. The application of millimeter-wave requires high bandwidth and gain to increase the traffic and users for millimeter-wave and 5G technology. The application of millimeter waves requires a high gain and bandwidth to achieve the requirements of traffic and users increasing for 5G technology and existing millimeter-wave. High-gain and power handling are provided by waveguide slot antennas. Three waveguide structures which are two waveguide antennae and a waveguide horn have been simulated by using CST and fabricated by a 3D printer. The tilt technique has been used with a waveguide to increase the bandwidth and gain of an antenna. A waveguide with broad wall tilt slots has one diction beam while a waveguide with broad and narrow wall tilt slots has two direction beams, each length of the wall enough to distribute six symmetric tilt slots. The gain of 14.3 dB and 1.9 GHz bandwidth are recorded for an antenna with broad wall tilt slots with one beam. While the waveguide with broad and narrow wall tilt slots achieved a gain of 13.9dB and a bandwidth of 1.9 GHz. The proposed antenna is a decent candidate for use with millimeter waves.

“…Antennas are an essential component of wireless technology. Their application in 5G communication is highly dynamic depending upon different specific requirements such as broad bandwidth [2], [3], polarization agility, reconfigurability [4], etc., along with common basic parameters. To satisfy the large throughput requirement for a 5G mobile terminal, a multiple antenna-element based MIMO antenna array is employed in the mobile terminal, which leads to the three main aspects of the 5G mobile terminal MIMO antenna, namely, antenna placement, bandwidth, and compatibility for users.…”

An eight-element wideband multiple-input multiple-output (MIMO) antenna for the fifthgeneration (5G) mobile terminal is proposed. The antenna elements are placed along both long side edges of the mobile terminal with a profile of 6 mm. The proposed monopole-inspired antenna element shows a good impedance match, isolation, and diversity parameter across a very wide bandwidth of 78 % (3.2-7.3 GHz), and it can cover the 5G NR n77/n78/n79/n96, LTE 46, and WLAN 5 GHz bands. The result shows that the MIMO antenna can offer inter-element isolation better than 12 dB, envelope correlation coefficient (ECC) below 0.069, and a peak channel capacity of 42.7 bps/Hz across the desired 5G bands. The specific absorption rate (SAR) analysis of the proposed MIMO antenna with a human head has exhibited SAR levels (0.41 W/Kg and 0.33 W/Kg at two resonating frequencies 3.9 GHz and 5.8 GHz, respectively) much lower than the Federal Communications Commission (FCC) permissible limit (1.6 W/Kg over 1 gram tissue).INDEX TERMS 5G mobile, MIMO antenna, specific absorption rate (SAR), sub-6 GHz, wideband.
