“…For mm-Wave 5G cellular handsets working in the 28 GHz band, a DRA is suggested in [14]. In [15], with the help of corrugated metamaterial surface the isolation is improved, but the radiation pattern is not stable, and similarly in [16], a 4 × 4 MIMO antenna is proposed for 5G communication application. In [17], applications for 4G Long Term Evolution (LTE) and mm-Wave 5G are proposed for corner bent MIMO antennas.…”

A rectangular Dielectric Resonator Antenna (DRA) four element Multiple in Multiple Out (MIMO) is proposed for 5G application, and each element is supplied with slot-coupled microstrip feed. The entire construction has a dimension of 20 mm × 40 mm. Four Dielectric Resonators are mounted exactly above the slot. In order to improve the isolation, metamaterial is printed on top of the dielectric resonators, which move away the solidest coupling fields. As the metamaterial structure interacts with electromagnetic fields, field distributions are disturbed which results in reduction of coupled fields. Since the metamaterials are printed on top of the dielectric resonator, the proposed antenna structure has the simplest and compact design. The proposed structure is operating with an impedance bandwidth of 2.23 GHz with operating range from 26.71 GHz to 28.91 GHz, which covers the 28 GHz (27.5 GHz-28.35 GHz) band allotted by Federal Communications Commission (FCC) for 5G application. With all four-port excitation, the proposed structure shows a broadside radiation pattern with gain above 7 dBi in the entire operating bands. The Envelope Correlation Coefficient (ECC) for operating bands is within the target value. They are designed and fabricated to validate the proposed antenna. The simulated and measured values are nearly equal, which means that the proposed MIMO DRA is the right choice for mm-Wave 5G implementation.

“…In [38], a eight-elements-based Vivaldi antenna is presented that achieves a bandwidth of 3.95 GHz with a maximum gain of 11.32 dBi. In [39], an array that is based on metamaterial unit cells is excited using two dipole antennas in a MIMO configuration. The presented antenna covers a wideband of 5 GHz ranging from 26 GHz to 31 GHz with peak gain of 10 dBi.…”

In this work, four distinct antenna configurations for future-centric 5G applications are proposed. Initially, a single rectangular patch is designed to operate at the frequency of 28 GHz while maintaining a wide operational band. Performance of the antenna is improved by incorporating an array of identical rectangular elements resulting in a higher gain and wider bandwidth. The proposed arrangement consists of three rectangular elements realized using 0.508-mmthick Rogers RT/Duroid 5880 laminate. The bandwidth is further enhanced by increasing the number of radiating elements in the array from three to five. Evolution of the proposed design is concluded by stacking the superstrate layer above the five-element array structure, thereby improving the gain associated with the proposed configuration. The antenna covers the frequency band from 25.1 GHz to 30.5 GHz under consideration for 5G communications. The proposed antenna occupies a physical footprint of 3.5 × 3.5 cm 2. Performance of the presented antenna configurations is analyzed using different electromagnetic descriptors including bandwidth, reflection coefficient, gain, radiation patterns, and radiation efficiency obtained using Computer Simulation Technology Microwave Studio (CST MWS) software. The measured results, obtained after fabrication and testing, demonstrate good overall agreement with the simulated outcome. The formulated design is a prime candidate for deployment in 5G applications of the future.

“…ere are many works in the literature concerning this topic for low frequencies, such as [6][7][8][9]. However, we can find plenty of papers for high frequencies [10][11][12][13][14][15][16][17][18][19][20][21][22]. In this work, we chose the millimeter waves band, precisely 28 GHz, for several reasons.…”

This paper presents a compact Multiple Input Multiple Output antenna with high isolation and low envelope correlation (ECC) for fifth-generation applications using spatial diversity technique. The proposed MIMO antenna consists of two single antennas, each having size of 13 × 12.8 mm2, symmetrically arranged next to each other. The single and MIMO antennas are simulated and analyzed. To verify the simulated results, the prototype antennas were fabricated and measured. A good agreement between measurements and simulations is obtained. The proposed antenna covers the 28 GHz band (27.5–28.35 GHz) allocated by the FCC for 5G applications. Moreover, the isolation is more than 35 dB and the ECC is less than 0.0004 at the operating band, which means that the mutual coupling between the two elements is negligible. The MIMO parameters, such as diversity gain (DG), total active reflection coefficient (TARC), realized gain, and efficiency, are also studied. Thus, the results demonstrate that our antenna is suitable for 5G MIMO applications.
