“…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.…”

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.

“…Table I compares the proposed antenna with the folded dipole antennas reported in recently published papers. A compact vertically stacked FDA with a 12% bandwidth is proposed in [13] by utilizing a multilayer PCB technology. In [14], a planar antenna comprising two folded dipoles obtain a very stable gain around 4 dBi with a 20% bandwidth.…”

“…The mmWave antenna with many modules for different functions, such as display, data communications, and cameras, should be tightly configured within the narrow PCB space within the mobile unit. Therefore, the minimization of the antenna dimension including via-based antipodal antenna using a multi-layer PCB structure [9].…”

In this paper, we present a portable end-fire antenna array design for the fifth-generation (5G) mobile handsets that exploits a Vivaldi antenna and shows a wide fan-beam on the elevation plane. We make the proposed antenna array more efficient by printing on a 10-layer printed circuit board (PCB) lamination in a vertical direction of the ground plane edge. Using the proposed Vivaldi antenna array design, the radiation characteristics of 4×1 linear arrays are fabricated. To validate the feasibility, we perform simulations and experiments. Simulation results show that the total efficiencies of the antenna array are higher than about 8.16-9.46 dBi for the scanning range between 0° to 60°. Measurement results display that the antenna has S11 reply less than-10 dB in the frequency area of 27.5 to 28.5 GHz and wide beamwidth (130.8° in azimuth plan, 21.35° in elevation plan). There is a high accord between the calculated and measured results and we consider that the results in this study can be well achieved by designers who design the wide width high-speed antennas of 5G mobile terminals.
