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.

This paper presents a flexible multiple-input, multiple-output (MIMO) antenna with ultrawideband (UWB) performance for smart clothing applications. The MIMO antenna is comprised of four octagonal-shaped radiators with several slots loaded into them, and it offers a frequency range of 2.9–12 GHz. The unit cell has a size of 0.26λ0 × 0.164λ0 × 0.014λ0 and the MIMO antenna has a size of 0.48λ0 × 0.48λ0 × 0.014λ0, where λ0 corresponds to the lowest operating frequency. The radiation and diversity performances of the antenna are evaluated, and the obtained metrics are envelope correlation coefficient (ECC) <0.045, diversity gain (DG) >9.9 dB, total active reflection coefficient (TARC) <−14 dB, and channel capacity loss (CCL) <0.13 bits/s/Hz. The bending analysis of the MIMO antenna is performed. The specific absorption rate (SAR) of the MIMO antenna is also investigated, and the obtained values are 0.229 W/Kg (4 GHz), 0.253 W/Kg (7 GHz), and 0.463 W/Kg (10 GHz).

“…In recent years, the demand for antennas for use in automotive communication systems has continued to increase, which has caused research on the Internet of vehicles (IOV) [1], such as vehicle-to-everything (V2X), vehicle-to-vehicle (V2V), vehicle-to-network (V2N) and In-vehicle Infotainment (IVI) communication, to flourish [2,3]. In the future, the Intelligent Transportation System (ITS) will be able to obtain real-time traffic information, such as road conditions, road information, and pedestrian information through the connection of the Internet of vehicles and the base station, which can also improve driving safety, avoid traffic congestion, and improve transportation efficiency [4].…”

This paper proposes a simple and small-dimensioned antenna that can provide X band and Ku band for the low-earth-orbiting (LEO) satellite system in an Internet of vehicles system. The antenna is designed on the substrate Arlon DiClad 880. The antenna structure consists of an inverted triangle geometry and an inverted U-shaped slot. The dimensions of the antenna are 12.5 × 5 mm2, and the area of the substrate is 30 × 13 × 0.254 mm3. The antenna is easy to make, and the manufacturing cost is low. The measurement results of the reflection coefficient (lower than −10 dB) of the antenna show that the working frequency band can cover the X-band (10.87–12.76 GHz) and the Ku band (15.19–16.02 GHz). The measured and simulated results are fairly similar. The efficiency of the antenna in the X-band is about 50–80.8%. The efficiency of the antenna in the Ku-band is about 50–74%. The gains of the antennas are about 3.34–6.08 dBi and 3.50–4.65 dBi in the X-band and Ku band, respectively, and the highest gain is 6.08 dBi. The antenna design can realize the features of low cost and small dimensions in autonomous vehicles and vehicle networking communication system equipment and achieve good wireless transmission capabilities from vehicles to the base station in the IOV.
