In this paper, we design and simulate a 28/38 GHz dual-band multiple-input multiple-output (MIMO) patch antenna array that operates in the FR2 frequency band (28 GHz and 38 GHz). This antenna array comprises four similar patch antennas with a rectangular "L minus two slots" shape. In addition, it applies to 5G electronic components such as a smartphone. We used high-frequency structure simulator (HFSS) software to perform the design and simulation for this antenna. In addition, this proposed antenna array provides better performance, such as; bandwidth around 28 GHz is equal to 0.69 GHz and 38 GHz is equal to 0.86 GHz, equal gains 5. 9 dB at 28 GHz and 9 dB at 38 GHz, directivities are 6.3 dB at 28 GHz and 9.4 dB at 38 GHz, the efficiency of 95.38% at 28 GHz, and efficiency of 96.53% at 38 GHz.

“…As per the FCC different frequencies like 3.5 GHz,6.2 GHz,28 GHz,38 GHz,39 GHz and 47 GHz [5] are allotted for 5G communication. So, to develop patch antenna comparable with 5G, different researches have proposed their respective work, in [6], concave shaped patch surrounded by two mirror imaged Cshaped in MIMO configuration is suggested qualifying 28 & 38 GHz of frequency having gain of 7.46 and 8.56 dBi respectively. A reconfigurable 5G patch antenna having switching capability between 28 GHz and 38 GHz using PIN diode is proposed [7].…”

In the present work Aperture Coupled Feed (ACF) microstrip patch antenna for 5G communication is proposed. The proposed antenna has a very compact size of 2.2λg×2.2λg×0.3λg (mm3), it is printed on Rogers RT Duroid 5880 with Ꜫr =2.2. The antenna having two vertical layer of 0.8 mm separated by air gap of 0.035 mm. The upper edge of substrate has a circular ring patch working as radiator whereas bottom having no metallization. Upper portion of lower substrate has plus shape slot and at bottom is a rectangular feed line acting as feeder to patch antenna. The antenna operatable from 36.84 GHz to 46.78 GHz and having an operating frequency of 38.40 GHz. The overall B.W% achieved is 25.91% and peak gain observed to be 7.32 dB. The measured results are in close agreement with the simulated one. Prior to approaching ACF technique, a conventional microstrip patch antenna with circular radiator with size of 2.2λg×2.2λg×0.15λg (mm3), printed on single PCB of same material was considered. The antenna gets operatable from 33.07 GHz to 39.5 GHz and resonating at 38.02 GHz. The overall B.W% achieved is 17.10% and peak gain of 8.1 dB. Both antennas are good candidature for 5G Communications.

The present work proposes a novel design of a dual-band-printed antenna for operation at the millimeter-wave frequencies 28 and 38 GHz that are utilized for the modern and future generations of mobile communications. The antenna is composed of two radiating elements. The first element is the main patch that is fed through a microstrip line with inset feed, and the second element is a parasitic element that is fed through capacitive coupling with the main patch. The design parameters of the proposed antenna are optimized through a complete parametric study to give excellent impedance matching at 28 GHz over the band 27.7–28.3 GHz and at 38 GHz over the band 37.7–38.3 GHz. The surface current distributions at the two operational frequencies are investigated. The designed antenna is used to construct a four-port efficient multi–input–multi–output (MIMO) system. The MIMO system performance is investigated regarding the envelope correlation coefficient (ECC), diversity gain (DG), and the channel capacity loss (CCL) showing very good performance. The single-element antenna and the MIMO are fabricated and experimentally evaluated showing excellent impedance matching over the lower and higher frequency bands, which come in agreement with the simulation results. It is shown that the antenna produces maximum gain of 7.4 and 8.1 dBi at 28 and 38 GHz, respectively. The average radiation efficiencies of the proposed antenna are 88% and 88.8% over the lower and higher frequency bands, respectively. In addition, the coupling coefficients between the MIMO antenna systems are measured experimentally showing very low coupling values resulting in an efficient MIMO system that is suitable for future millimeter-wave (mm-wave) applications.
