“…Terefore, by arranging the semitransparent antenna elements orthogonally, the antenna provides better isolation without any decoupling structures and also has two polarization vectors (horizontal and vertical). (vi) Te CCL is found to be less than 0.2 bits/s/Hz unlike [31,32,34].…”

This paper presents the design and development of a semitransparent antenna that can be used in automotive applications to support multiple wireless services. The proposed quad-port multiple input multiple output (MIMO) antenna is comprised of four orthogonally arranged identical semitransparent antenna elements on a transparent substrate. The MIMO antenna covers the 2.4 GHz band and 3.2–15 GHz band, supporting automotive/wireless applications such as Bluetooth, Wi-Fi, intelligent transport system (ITS), advanced driver assistance systems (ADASs), vehicle to infrastructure (V2I), vehicle to vehicle (V2V), vehicle to network (V2N), and vehicle to device (V2D). The parameters such as envelope correlation coefficient (ECC), diversity gain (DG), total active reflection coefficient (TARC), and channel capacity loss (CCL) are studied to evaluate antenna diversity performance. The antenna has an ECC of less than 0.15, DG of more than 9.85 dB, TARC of less than −10 dB, and CCL of less than 0.2 bits/s/Hz. The developed antenna can be easily installed on the mirror and windshield of the vehicles. Also, the housing effect and on-vehicle performance of the antenna at various positions in a car are investigated.

“…Hence, to improve the error rate performance of MIMO wireless communication systems, the primary requirements for MIMO systems are low spatial correlation and high isolation between the antennas [12]. However, achieving the required isolation levels between antennas with connected ground structures is a very challenging task [13,14]. In [15], defected ground structure (DGS) with an antenna is used to improve the isolation between the antennas in MIMO systems.…”

Interconnected three-element and four-element wideband MIMO antennas have been proposed for millimeter-wave 5G applications by performing numerical computations and carrying out experimental measurements. The antenna structure is realized using Rogers 5880 substrate (εr = 2.2, tan δ = 0.0009), where the radiating element has the shape of an inverted L with a partial ground. The unit element is carefully designed and positioned (by orthogonally rotating the elements) to form three-element (case 1) and four-element (case 2) MIMO antennas. The interconnected ground for both cases is ascertained to increase the practical utilization of the resonator. The proposed MIMO antenna size is (0.95λ × 3λ) for case 1 and (2.01λ × 1.95λ) for case 2 (at the lowest functional frequency). Both the designs give an impedance bandwidth of approximately 26–40 GHz (43%). Moreover, they achieve greater than 15 dB isolation and more than 6 dBi gain with an ECC value lower than 0.02, which meets the MIMO diversity performance thus making the three-element and four-element MIMO antennas the best choice for millimeter-wave 5G applications.

“…CR performs dynamic spectrum management and thus increases the spectral efficiency. Because of the scaling down of wireless circuits, the need of next generation technologies like LTE with higher data rates is growing day by day [11][12][13][14][15][16][17][18]. So, designing a compact MIMO antenna to cover sub-1 GHz bands like LTE 700 without increasing the antenna size and decreasing its performance is one of the design challenges.…”

“…Additional extensions are also added on the ground which increases complexity and leads to parasitic resonances. Antennas for sub-6 GHz bands and IoT are presented in [14][15][16][17][18]. Though these antennas cover many important wireless bands, they do not cover sub-1 GHz frequency bands.…”

A 4-port planar multiple-input multiple-output (MIMO) antenna system design is proposed. The antenna elements are modified meandered wideband antennas which cover frequencies from 674 MHz to 1 GHz, 1.9 GHz to 2.1 GHz, 3.175 GHz to 3.476 GHz, 4.529 GHz to 4.761 GHz, and 5.254 to 5.513 GHz for long term evolution (LTE), Internet of Things (IoT), and sub-6 GHz applications and thus can be used for robotic navigation, logistics, healthcare, tracking, transportation, etc. Due to very small envelope correlation coefficient (ECC) between the ports (< 0.5), the MIMO configuration can be efficiently implemented which helps in increasing the data rates. It is very compact in size and thus can be used for portable handheld devices. Since there is the problem of current localization due to common ground, the future work aims at minimizing coupling and improving the impedance matching using novel decoupling networks. These MIMO antennas are connected to a common slotted ground plane. Antenna simulation has been done using Computer Simulation Technology (CST) Microwave Studio Suite simulator. A low cost FR-4 substrate with dimensions 65 mm × 90 mm × 1.6 mm has been used for antenna fabrication, and experimental results are obtained using an anechoic chamber and a vector network analyser. ECC and realized gain of the antenna are also obtained experimentally and are almost similar to the simulated results.
