Two SPEM (Shorted‐Planar‐Elliptical‐metal) antenna which is utilized for UWB applications are placed closely for MIMO applications 5 and by using fence‐type stub between the ground of MIMO antenna provides isolation 6 . T‐shaped stub attached to the ground of multi‐band MIMO antenna results in high isolation.…”

In this reported work, two dual notched bands from 3.39 GHz to 3.92 GHz and from 4.43 GHz to 5.48 GHz for the WiMAX band (3.3–3.8 GHz) and for (lower) WLAN band (5.15–5.35 GHz) MIMO antenna with adjacent/orthogonal orientations has been investigated. Also, the proposed antenna is capable of controlling these notched bands whenever the need for power saving arises by reconfiguring them using PIN diodes. The issue of isolation between the radiating elements has been overcome by placing the radiating structures in the adjacent and orthogonal arrangement. The proposed antenna is characterized proving an average gain of 4.15/4.37 dBi and maximum radiation efficiency of 91/87% for adjacent/orthogonal orientation. The proposed antenna also shows good agreement with simulated and measured impedance bandwidth, diversity performances in terms of ECC, DG, TARC, and CCL for which values are well below the permissible range.

In this communication, a wideband 2-Port Multiple-Input-Multiple-Output (MIMO) antenna of the dimension of 0.13 λ0 × 0.68 λ0 × 0.02 λ0 mm3 (λ0, measured at a lower frequency is 4.43 GHz) is investigated for the C-band and Partial X-Band Applications. The concept of defective ground is introduced to enhance the impedance bandwidth by engraving the rectangular slots. In the proposed configuration a mender line is incorporated as a decoupling network between the antenna elements to enhance the isolation. The quarter wavelength long stepped impedance matched transmission line is used to excite the proposed configurations. The percentage impedance bandwidth of the proposed antenna is 83%. To explore the diversity of the MIMO system the ECC, DG, TARC, and CCL are reported. Excellent agreement between simulation and measured results is obtained, justifying the MIMO antenna's applicability for wireless applications.

“…For example, the designed MIMO antenna in [21] operates within UWB frequency band and has electrical dimensions of 0.41λ × 0.25λ mm 2 . The electrical dimensions of the UWB MIMO antenna in [23] are 0.41λ × 0.47λ mm 2 and in [24][25][26] the dimensions are 0.25λ × 0.33λ mm 2 , 0.96λ × 1.11λ mm 2 , and 0.41λ × 0.33λ mm 2 respectively. A number of challenges are being faced in the design of MIMO antennas.…”

“…Most of these antennas possess large dimensions, have low isolation enhancement and low %BW and gain. For example, in [23] the MIMO antenna possesses large physical dimensions of 58.6 × 46 mm 2 with a mutual coupling of <−13 dB, in [25] the mutual coupling is <−17 dB whereas the size of the MIMO antenna is 50 × 80 mm 2 and the isolation enhancement of 40 × 68 mm 2 MIMO antenna designed in [22] is less than −15 dB.…”

This paper presents a compact planar multiple input multiple output (MIMO) antenna for super wide band (SWB) applications. The presented MIMO antenna comprises two identical patches on the same substrate. Dimensions of the MIMO antenna are 0.17λ × 0.20λ × 0.006λ mm3, with respect to the lowest resonance of 1.30 GHz. The SWB antenna was manufactured using F4B substrate having a dielectric constant of 2.65 that provides a percent impedance bandwidth and bandwidth ratio of 187% and 30.76:1, respectively. The mutual coupling between the antenna elements is suppressed by placing a T-shaped corrugated strip in the mid of two antenna elements. The proposed MIMO antenna exhibits maximum diversity gain of 10 dB, low mutual coupling (<−20 dB), low envelope correlation coefficient (ECC < 0.02), efficiency >80%, and low reflection coefficient (<−10 dB) in the SWB frequency range (1.30 GH–40 GHz). The presented antenna is a good candidate for SWB applications. The designed antenna has been experimentally validated, and the simulated results were also verified.
