E-Shaped H-Slotted Dual Band mmWave Antenna for 5G Technology

Abstract

The aim of this work is to propose a dual band millimeter wave (mmwave) MIMO antenna system for 5G technology. In addition, the arrangement of the antenna elements in an array should be in such a manner that without using the traditional decoupling structures and/or techniques, a reasonable isolation level must be achieved. To demonstrate this, a system consists of four radiating elements that are etched on a 0.508 mm-thick Rogers-5880 substrate. The dielectric constant of the substrate is 2.2 and the loss tangent is 0.0009. Each radiating element consists of three parts; an E-shaped patch, an H-shaped slot within a patch, and a transmission line. The system is resonating at two different mmwave frequencies, i.e., 28 GHz and 38 GHz with a minimum port isolation of 28 dB. The mean measured gain is found to be at 7.1 dBi at 28 GHz and 7.9 dBi at 38 GHz with average efficiency, and envelope correlation coefficient (ECC) of the system at 70%, and 0.0005 respectively. The proposed system is designed and simulated in a full-wave electromagnetic wave software Computer Simulation Technology (CST), fabricated using LPKF D104 milling machine, and measured using R&SZNA67 vector network analyzer. An excellent agreement is observed between the simulated and the measured results and a detailed comparison with the previous works is also presented. Due to attributes such as low-cost, easy to fabricate, and dual-band, it is believed that this system will find its application for future 5G systems.

A New mm-Wave Antenna Array with Wideband Characteristics for Next Generation Communication Systems

“…These antenna arrays include higher numbers of radiating elements with low-loss feeding networks [7,8]. There are several antenna systems reported in the literature [9][10][11][12][13][14][15]. These antenna systems include substrate integrated waveguide (SIW) antenna systems, air filled gap structures (AFGs), and planar structures.…”

MIMO Antenna System for Modern 5G Handheld Devices with Healthcare and High Rate Delivery

“…Here, we have assumed uncorrelated transmitting antennas and identical independent channels with Rayleigh fading environment. From Figure 8, it is evident that the calculated channel capacities are about 38 bps/Hz within the desired frequency range, which is 2.9 times higher than the 4 × 4 MIMO system [24]. Similarly, the antenna efficiency of the single element is around 80%, while for the corner elements it is around 65% and for the elements in the middle, it is around 42%-40%, as shown in Figure 9.…”

Design of a Millimeter-Wave MIMO Antenna Array for 5G Communication Terminals

“…This technology will be using the unused millimeter waves spectrum, ranging from 30–300 GHz, in order to achieve higher data rates and bandwidths. Using higher frequencies for the next generation will result in free space path loss, which indicates that higher frequencies are greatly affected by atmospheric losses [ 7 , 8 , 9 , 10 ]. This means that higher frequencies are greatly suffering from atmospheric attenuation.…”
