This article presents the design, analysis, and realization of a new printed multiple‐input‐multiple‐output (MIMO) antenna with a very high gain and wide bandwidth for the millimeter‐wave (mm‐wave) 28/38 GHz fifth generation (5G) new radio (NR) applications. The proposed MIMO antenna consists of four identical patch elements in a 2 × 2 configuration to achieve high gain with wide operating bandwidth. The proposed antenna holds an attractive compact size of 31.891 × 37.528 mm2. The proposed MIMO configuration is designed on a 0.508 mm thick Rogers‐5870 substrate material with a loss tangent of 0.0009 and a relative dielectric constant of 2.33. An effective technique for folding the feed line and applying a new protruding ground is introduced to obtain good mutual coupling. The fabricated prototype of the proposed antenna is tested to verify the simulation results for the validation of the suggested design approach. The suggested MIMO antenna exhibits −10 dB impedance bandwidth of 2.6 GHz (27.4–30.0 GHz) and 3.3 GHz (36.7–40.0 GHz) to cover the intended frequency range for 5G applications with isolation less than −22 band peak gains of 18 and 14.5 dBi at 27.5 and 38.8 GHz, respectively. To validate the MIMO performance of the proposed antenna several MIMO diversity parameters such as mean effective gain (MEG), envelope correlation coefficient (ECC), and diversity gain (DG) are evaluated. Determined results indicate ECC < 0.001, DG > 9.995, and an average MEG of −3 dB at the operating bands. The proposed antenna exhibits good agreement between the simulated and measured results, which confirm its suitability for forthcoming mm‐wave 5G MIMO systems and services.

This research presents a flower-shaped design of a multi-input multi-output (MIMO) antenna with dual wide operating bands in the millimeter-wave (MMW) region proposed for 5G applications. The antenna system consists of a quad-port antenna array placed with a 90-degree shift; it was etched on a low-cost FR-4 dielectric substrate with a full size of 22221 mm 3 . The objective of this work it to enhance the bandwidth of the proposed MIMO antenna as well as to increase the antenna gain. To increase the gain, we used multiple single antennas and to enhance the bandwidth we added some slots to the suggested antennas. The array antennas are designed to provide dual-band operation at the frequencies of 29 GHz (n257) and 39 GHz (n259). The results are simulated using HFSS, acceptable gain reaches 3.04 dB and 8.11 dB in the first and second bands, respectively, while the impedance bandwidth achieved by the design is about 1600 MHz (28.9-30.5 GHz) at 29.8 GHz and about 2330 76 GHz) at 39.6 GHz with a reflection coefficient S11 of about -16.20 dB and -19.27 dB, respectively. The proposed antenna can be a desire choice for 5G applications because of its low cost, small size, high performance in terms of bandwidth and gain.

A cost-effective antenna-in-package design based on a 4 × 4 dual-polarized high isolation patch array for 5G mmWave applications is proposed in this paper. To obtain a cost-effective design, we devised a four-layer metal stack-up structure with dielectric materials consisting of one TLY-5 polytetrafluoroethylene (PTFE) and two FR-4 epoxies. The devised stack-up exhibits a simple and compact geometry due to the small number of layers, which allows the design to be manufactured using a low-priced standard printed-circuit-board process. Additionally, the employed material combination in the stack-up design possesses a high-end PTFE only in the region with the antenna radiators, which enables good antenna radiation performance at an affordable price. In addition, to design a high-isolation patch array for dual-polarized applications using the low-layer stack-up structure, we employed capacitive probes, defected ground structures, and the rotated-fed method in the proposed array design. With these techniques, the designed array exhibited excellent performance with respect to both port-to-port isolation and crosspolarization isolation. The mechanism of improvement in port-to-port isolation was clearly described using the established equivalent circuit model of the proposed structure. As a result, the fabricated antenna-inpackage has the reflection coefficients of less than -10 dB in the targeted frequency range of 26.5-29.5 GHz and has a peak gain of 17.37 dBi at 28 GHz. The measured port-to-port isolations and crosspolarization isolations are higher than 22.63 and 30 dB in the targeted frequency band, respectively.INDEX TERMS 5G mm-Wave, antenna in package (AiP), capacitive probe, defected ground structure (DGS), dual-polarized patch antennas
