“…A detailed comparison with published antennas in terms of resonant frequency point, radiation efficiency, antenna size and port isolation is shown in Table I. Among them, the high isolation brought by the decoupling method proposed in [1], [9], [11], [17] is slightly inferior to 27.5 dB in this paper. In [3], [5], [10], [14]- [16], perfect isolation and high radiation efficiency are obtained.…”

“…Then the feature of high isolation within broadband is obtained in [16]. In [17], a linear antenna array is proposed by placing the patch antenna and the monopole antenna at intervals. Attributes to the periodic distribution, the mutual coupling between nonadjacent patch antennas cancels the coupling between the patch antennas and the adjacent dipole antennas.…”

A novel decoupling method combining magnetic coupling and electric coupling is proposed in this paper to design a miniaturized two-element antenna array. Different from the traditional planar decoupling structure, a three-dimensional quasi-split resonant ring decoupling structure which can realize electric coupling is introduced. The quasi-split resonant ring is composed of two meandered antenna elements printed on the top and bottom of the substrate. The other decoupling structure is composed of two parasitic patches, which realize magnetic coupling with the open end of the dipole element in the opposite plane. By properly controlling the strength of magnetic coupling and electric coupling, the induced currents can cancel each other out, thereby enhancing the isolation between adjacent ports. Compared with the antenna array employing the planar decoupling method, the size of the antenna array in this paper is significantly reduced by half. In terms of S-parameter and near-field radiation, the simulated results of the full-wave analysis are compared with the measured results. Essentially identical results successfully verify that the antenna achieves an isolation up to 27.5 dB and omnidirectional radiation mode in the resonant bandwidth of 1.76-1.80 GHz.INDEX TERMS antenna array, magnetic coupling, electric coupling, decoupling structure, parasitic patch, near-field.

This work investigates a high-isolation Orthogonal Printed Elliptical Slot Antenna (OPESA) array with Multiple Inputs and Multiple Outputs (MIMO). A unique composite Electromagnetic Band-Gap (EBG) structure consisting of a vertical six rings positioned between single element antennas were devised and investigated with the aim of reducing mutual interaction between antenna components. A distinct feeble electric field that could successfully inhibit the Mutual Coupling (MC) among the antenna components is easily produced by the suggested composite EBG construction. One type of decoupling constructions throughout the antenna growth was carefully examined at together the theoretical and physical levels in order to offer a clear representation of the suggested antenna array’s design concept and decoupling technique. The antenna array design process was cleverly separated into three stages. In order to verify the suggested decoupling idea, the array Scheme was constructed, assessed, and measured. Studying the antenna gain, radiation pattern, and reflection coefficient, it was found that the simulated and measured findings were very consistent. According to the models, the array has an extreme radiation efficiency of about 91%, a minor value of Envelope Correlation Coefficient (ECC < 1.8 × 10−4), and a maximal gain of 11.5 dBi. The electrical size, highest isolating grade and the recommended MIMO antenna’s 90 dB isolating bandwidth (BW) were assessed. The planned antenna has several appealing features that set it apart from previous similar designs. These features include a low design complexity, a great Diversity Gain rate (DG > 9.99 dB), the BW of the proposed antenna extends from 25 GHz to more than 40 GHz, an enormously great isolation level (about 90 dB), and compressed dimensions (51 mm × 30 × 1.6 mm). For verifying the recommended antenna for MIMO. the suggested MIMO antenna design’s radiation efficiency, a thorough time-domain study is suggested.
