It is clear that the majority of the MIMO antenna designs described in [15][16][17][18][19][20][21][22][23][24] are larger than the intended antenna, which restricts their suitability for use with contemporary small communication devices. However, only a small number of designs have been able to achieve a compact structure with low gain.…”

This paper suggests a dual-band 28/38 GHz four element MIMO array based on dual-mode planar monopole antennas for 5G wireless applications. The design structure contains four planar monopole antennas; located at the corners on a 20×20 mm 2 size Rogers RO4003 substrate with a dielectric constant of 3.55. The proposed planar monopole antenna has the shape of a crescent. In order to achieve the desired behavior and performance, we engraved two rectangular slots on both sides and also added a notch at the bottom. In addition, we used a partial ground plane to enhance the isolation. Signi cant isolation ( > − 23 dB) is achieved between antenna elements by employing spatial and polarization diversity techniques. To validate the design concept, a prototype of the fourelement MIMO array is designed, fabricated, and measured. The experimental results show that the proposed antenna can cover the 27.25-29 GHz and 34.5-41 GHz bands with good isolation and high e ciency. Furthermore, the radiation pattern, the realized gain and the channel capacity are also studied. According to the reached results, the proposed MIMO antenna may be a suitable application-oriented design for 5G MIMO applications at the millimeter-wave range.

The present study introduces an innovative MIMO (multiple input multiple output) antenna for fifth generation (5G) wireless applications operating in the millimeter wave (mm-Wave) band. The antenna is designed using a crescent concept on three superposed balls, similar to the symbol on top of a mosque minaret. The proposed design is developed on a 20×10 mm2 FR4 substrate with a dielectric constant of 4.4 and a tangent loss of 0.002. The frequency range of the proposed antenna is between 27.3 to 28.9 GHz, and it offers excellent isolation (> 25 dB). The authors have conducted a parametric analysis and surface current distribution to optimize the parameters and analyze the coupling between the elements. The performance of the design is evaluated based on various criteria such as efficiency (> 95%), peak gain (> 14 dBi), and radiation patterns (E and H fields). The diversity parameters (ECC, DG and CCL) have been calculated and verified, and the results of the fabricated prototype have been compared to the simulated results, which are found to be in good agreement.

A compact wideband MIMO antenna obtained by breaking up an intact rectangular patch into a 2 × 5 small patch array with connected strips is proposed for 5G mobile terminals. The diagonal small patches are connected with the metal strips respectively, so as to constitute an interleaved double branch composed of a main branch and a parasitic branch, thus achieving compactness. The main branch fed by two ports operates at 4.5 GHz, and the parasitic branch coupled by the main branch achieves a lower resonant frequency of 3.35 GHz, thus widening the bandwidth. The small patches in the middle are connected to the ground to improve the isolation. A short length of 21.5 mm (about 0.24 wavelength of the lower‐edge frequency) of the proposed antenna pair is realized. Besides, an eight‐element MIMO antenna is designed and fabricated. Measured results show the reflection coefficients are lower than −6 dB, and the transmission coefficients between every two ports are lower than −10 dB in the 5G N77/N78/N79 bands (3.3–5.0 GHz). The average total efficiencies are 70.4% and 63.8% for antenna 1 and antenna 2, respectively. The ECCs are lower than 0.15.
