“…It is feasible to enjoy the advantages of both codings and decoding the signal correctly. 2,3 In the 2.3-2.4 GHz operating range, the mushroom structure in a four-element MIMO antenna may provide up to −40 dB isolation. 4 The two quasi-self-complimentary MIMO antennas are used to attain very broad bandwidths.…”

The presented article represents the rudimentary-shaped effective 1 × 2 MIMO antenna structure. The five variation types in the ground region shape are analyzed. The structure's total dimensions are 40 × 36 × 1.6 mm 3 . For efficiently manufacturing, the low-profile substrate FR4 is employed, and the reflectance response of a simulated and modelled design is compared. The placement of two T-shaped slits in the ground area aids in achieving a wider bandwidth, multiband response, excellent Gain, and directivity. Overall, the PW:4 has a minimum reflectance coefficient of −34.54 dB, a broad bandwidth of 3.38 GHz, a peak gain of 13.02 dB, maximum narrow band isolation of 62 dB, and a maximum normalized directivity of 156°. The Envelop Correlation Coefficient, Channel Capacity Loss, Total Active Reflection Coefficient, and Diversity Gain for MIMO design are also examined. These findings indicate the provided design's behavior as per the standard requirements.

“…However, as the elements are closely spaced to each other, the mutual coupling effect becomes sturdy and in order to mitigate this effect, various isolation techniques have been reported to reduce the mutual coupling between elements [15][16][17]. CPW and ACS feeding techniques have been utilized in several literature reviews to achieve the compactness of the MIMO antenna with an improved performance [18][19][20][21][22][23]. In [18], the antenna structure is composed of eight elements and is fed by CPW for operation at sub 6 GHz 5 G wireless communication.…”

In this paper, a compact 4-port band-notched multi-input-multi-output (MIMO) antenna with asymmetric coplanar strip (ACS) feed is presented for ultra-wide band (UWB) applications. The MIMO antenna is comprised of four semi-elliptical radiators with ACS feed for UWB applications and it is printed on inexpensive FR4 substrate of size 48 × 52 mm2 with ɛr = 4.4 and 1.6 mm height. The impedance characteristics of the suggested MIMO antenna ranges from 2.7 to 11 GHz with a band-notched behavior from 3 to 4 GHz to reduce the interception with WiMAX applications, and the isolation level over the achieved band is more than 20 dB between any two adjacent elements. Moreover, the radiation pattern of the proposed UWB antenna is almost omnidirectional with an average realized gain of 3.5 dBi over the entire achieved frequency band. The proposed ACS-fed antenna is confirmed by fabricating and measuring it's impedance and radiation characteristics. Finally, good consistency between simulation and measured outcomes is obtained confirming the validity of the MIMO antenna for real-life UWB wireless systems.

“…A resonator structure between a radiating element [14] and a rectangular strip in the ground are different methods published for the improvement of isolation [13]. Four-element MIMO configurable radiators are discussed in [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] where different methods of isolation are used. In [16], orthogonally placed radiators required the absence of any decoupling structure and still maintained a better isolation.…”

“…Different decoupling techniques have also been reported such as double-decoupling branches placed orthogonally [21], decoupling elements between two radiators [22] and the orthogonal placement of radiators to further improve isolation [23][24][25][26][27][28][29]; circular arc-type grounded stubs also achieved a better isolation [30]. In [31], the absence of a decoupling structure was observed; by placing the four radiating structures orthogonally, a higher isolation was achieved. A flower-type radiating patch antenna has also been reported in [30] that had the capability of mitigating three interfering bands and provided a useful bandwidth of 7.83 GHz.…”

This research article reports a compact fractal 4 × 4 UWB extended bandwidth MIMO antenna with physical dimensions of 44 × 44 mm2 for high-speed wireless applications. The reported antenna comprises four fractal radiating elements that are symmetrical and placed orthogonal to each other with a respective rectangular ground printed on the opposite plane. A higher isolation is achieved between the radiating elements by the placement of a fractal patch orthogonally and no separate decoupling structure is required. The antenna offers a −10 dB transmission capacity of 2.84–15.88 GHz. The fractal radiating element, which is embedded by an inverted T-type stub placed within a rectangular slot and an etched rotated C-type slot, provides band-stop filters for WiMAX (Worldwide inter-operability for Microwave Access) and WLAN (wireless local area network)-interfering bands. The key parameters of diversity performance are compared by simulation and measurement (fabricated prototype) of ECC (envelope correlation coefficient), DG (directive gain), TARC (total active reflection coefficient) and CCL (channel capacity loss). The antenna offers an omnidirectional radiation pattern with an average gain of 3.52 dBi.
