“…Besides, the H-plane co-polarization and cross-polarization patterns are almost identical to those from Port 1 due to the evenly shape of the two radiating elements. As depicted in Figure 8 showing the simulated realized gain, except at the notched bands, a consistent gain is achieved that is better than the ones achieved in [32][33][34]. The diversity performance of the MIMO antenna can be usually estimated by the envelope correlation coefficient ECC and the diversity gain DG parameters.…”

This paper introduces a novel compact planar Ultra-Wideband (UWB) Multiple-Input-Multiple-Output (MIMO) antenna with dual-band notched performance for Surfaces Penetrating (SP) application. To avoid interference from co-existing systems, two notched bands are introduced by including strips inside the radiating patches. The two ports MIMO antenna is printed on the low-cost FR4 substrate having a compact size of 56×32.47×1.5 mm3. The measured results indicate that the −10 dB bandwidth of the proposed MIMO antenna covers a wide bandwidth from 1.57 GHz to 12.4 GHz (155.05%) with dual-band rejection (2.04 GHz – 3.98 GHz and 4.8 GHz – 6.22 GHz). The effects of numerous construction and decoration surfaces on the antenna’s reflection coefficients are measured. Gypsum, White Portland Cement, Slate, Marble, Wood and Reinforced Concrete were tested. A good penetrating capability is measured which confirms the aptitude of the proposed MIMO antenna to work as SP antenna.

“…Envelope correlation coefficient (ECC) is used in MIMO terminology as an indicator of the good isolation between the elements composing the multi-antenna system. ECC -expressed by 𝜌 𝑒 -can be calculated from S-parameters of the MIMO system as described in (4) [17], [18].…”

<span lang="EN-US">This paper presents a four-element frequency reconfigurable antenna system that is novel in terms of gathering both underlay and interweave cognitive radio in a single multiple input, multiple output (MIMO) design. Built on a 50×38×0.8 mm3 Rogers RT/Duroid 5880 substrate, this system is constructed of two scanning elements to sense ultra-wide band (UWB) with controllable band notching capabilities and two elements act as communication antennas. Eighteen MIMO modes can be provided depending on the state of the five positive-intrinsic-negative (PIN) diodes in each sensing antenna and the four PIN diodes in each communication antenna. These include a scanning UWB mode, fourteen modes to notch WiMax/Cband/<a name="_Hlk120169348"></a>wireless local area network (WLAN)/Xband/ITU in single/dual/triple/quad band rejection states and three interweave modes where each targeting one of the regions of WiMax/Cband/WLAN. Simulated by CST v.10; results like input reflection coefficient and realized gain verify system's capability to work in each operation mode. Moreover, mutual coupling, envelope correlation coefficient and diversity gain all evidence the performance of the proposed system as a MIMO system. Results, simple and compact profile, wide and flexile range of MIMO operation modes in line with the novelty to handle both underlay and interweave cognitive radio all nominate this system as promising to fulfill the needs of modern wireless communications.</span>

“…A MIMO antenna with two ports is investigated to attain triple band notches by inserting open-ended slots of quarter wavelength on the radiator [30]. A Compact two port MIMO Antenna with quad band notches is achieved by means of L shaped slots, circular ring slots on radiator, and two C shaped slots in the vicinity of tapered feed line [31]. A two port UWB-MIMO antenna with four band notches is attained by making use of L and C shaped slots and CSRRs.…”

A compact wideband operating from 3 to 20 GHz MIMO antenna with quadruple notches is presented in this paper. The elements in MIMO configuration are arranged in orthogonal fashion with each other to minimize the coupling effects. The antenna consists of circular rings and a modified microstrip feed. By engraving a crescent shaped slot, split ring-shaped slot, circle shaped slot in the circular monopole, rectangular spiral shaped slot engraved along the feed line, quadruple notches are attained. The antenna operates from 3 GHz to 18 GHz with notches in the range of 3.3 GHz-4.2 GHz centered at 3.5 GHz, 4.5 GHz-5.5 GHz centered at 4.9 GHz, 6.2 GHz-7.3 GHz centered at 6.6 GHz, and 8.1 GHz-8.8 GHz centered at 8.5 GHz. The element has a very compact size of 0.28λ × 0.22λ × 0.016λ at 3 GHz and is hence suitable for portable devices.
