“…The main design challenges of MIMO antenna systems for handheld devices are, firstly, the compactness due to limited space and, secondly, the reduced coupling between the antenna elements. Despite the fact that an MIMO antenna system increases the theoretical capacity of the system, it is degraded if the signals received at different antenna elements are correlated [ 8 ]. The system fails to provide the diversity gain if the envelope correlation coefficient (

) exceeds 0.5 [ 9 ].…”

A compact four-element dual-band multiple-input and multiple-output (MIMO) antenna system is proposed to achieve high isolation and low channel capacity loss. The MIMO antenna was designed and optimized to cover the dual-frequency bands; the first frequency band is a wide band, and it covers the frequency range of 1550–2650 MHz, while the other frequency band covers the 3350–3650 MHz range. The measured wide-band impedance bandwidths of 1.1 GHz and 300 MHz were achieved in the lower and upper frequency bands, respectively. The proposed structure consists of four novel antenna elements, along with a plus-sign-shaped ground structure on an FR4 substrate. The overall electrical size of the whole dual-band MIMO antenna system is 0.3λ(W) × 0.3λ(L) × 0.008λ(H) for the lower frequency band. It achieved greater than 10 and 19 dB isolation in the lower and upper frequency bands, respectively. The antenna system accomplished an envelope correlation coefficient of |ρ|≤0.08 in the lower frequency band, while it achieved |ρ|≤0.02 in the higher frequency band. The computed channel capacity loss remained less than almost 0.4 bits/s/Hz in both frequency bands. Therefore, it achieved good performance in both frequency bands, with the additional advantage of a compact size. The proposed MIMO antenna is suitable for compact handheld devices and smartphones used for GSM (Global System for Mobiles), UMTS (Universal Mobile Telecommunications Service), WCDMA (Wideband Code Division Multiple Access), LTE (Long Term Evolution), 5G sub-6 GHz, PCS (Personal Communications Service), and WLAN (wireless local area network) applications.

“…This problem can be solved by introducing band stop filter circuits into UWB devices, but this increases the system cost and size [12]. Numerous UWB-MIMO antenna designs with band notch behavior have been reported [13][14][15][16]. In [13], a U-shaped slot is inserted on the surface of the antenna element to obstruct the current distribution at 5.5 GHz.…”

In this paper, a novel design of a small printed Ultra-Wideband (UWB) Multi-Input Multi-Output (MIMO) antenna with a wide impedance bandwidth from 3.05 GHz to 11.65 GHz is introduced. The newly designed UWB MIMO antenna has an isolation enhancement of more than −15 dB between the two elements. This isolation is achieved by inserting a three-line stub on the ground plane between the two radiating elements. In addition, these parallel lines improve the impedance matching and the bandwidth of this structure. Dual band notched characteristics are achieved for the 5G band (3.6 GHz) and Wi-fi 6E application (6 GHz), by etching a complementary split ring resonator (CSRR) in both the truncated square patch elements and by loading the split ring resonator (SRR) on the ground plane at the back of antenna, respectively. The SRR and its complement are metamaterials structures, showing the behavior of an LC resonator circuit. The hybrid technique improves impedance matching, bandwidth, minimizes the mutual coupling in UWB frequency range, and delivers dual-notch characteristics. The simulation and measurement results of the proposed antenna with a good agreement are presented. The proposed structure exhibits high performances in terms of envelope correlation coefficient (ECC), diversity gain (DG), efficiency, total active reflection coefficient (TARC), and channel capacity loss (CCL) except the notched band.

“…Incorporation of different slots like L‐shaped, 5 U‐shaped, 3,6 V‐shaped, 7 planner inverted F‐shaped antenna, 8 cup‐shaped, 9 hat‐shaped 10 in the antenna help in analysis of notch filtering functionality. Other techniques including split ring resonator, 11 tuning stubs, 12 and electromagnetic band gap (EBG) configurations 13 are capable of generating band reject behavior.…”

This letter introduces a compact elliptically‐slotted patch antenna with Ku band reject characterizes. The proposed antenna works in the super wide range of frequency band stretched beyond the UWB. The slots in the radiating patch take the shape of ellipse and are present in such a manner that the double of their ellipticity follow the Fibonacci series. The perturbed‐diamond‐shaped patch without the slot radiates in the frequency range from 4.19 to 21.88 GHz with a bandwidth of 17.67 GHz. The same patch antenna with the elliptical‐slots rejects Ku band from 12.89 to 16.22 GHz. We have analyzed the notch frequency variation with respect to the slot area using Ansys HFSS V.20 electromagnetic simulator software for verification.
