Abstract

The realization of Internet of Vehicles (IoV) supports the development of intelligent transportation in a smart city. Existing and coming wireless networks allowing vehicles connect to terrestrial base stations (BS), autonomous aerial vehicles (AAV), and satellites networks are the key to accomplish this ambitious goal of IoV connectivity. The wireless industry as well as the vehicle leaders are now seeking antenna innovations to support the integration of sub-6 GHz (vehicles-to-AAV), 24 GHz (vehicles-to-BS), and 20/30 GHz (vehicles-to-satellites) networks. Here, we introduce a new triple-band high-gain antenna, which produces the operating frequencies at sub-6, K- and Ka- bands for the first time. The triple-band performance is realized on a shared-aperture configuration by hybridizing a sub-6 GHz Fabry-Perot Cavity antenna (FPCA), a K-band folded reflectarray antenna (FRA) and a Ka-band reflectarray antenna (RA). Three kinds of meta-atoms (MAs) with distinct functions at different frequency bands are used to constitute the respective three functional metasurfaces of the proposed shared-aperture antenna. For demonstration, a prototype is fabricated and measured. The measured effective bandwidths (for the reflection coefficient ≤ −10 dB and the gain variation ≤ 3 dB) are 5.62 to 5.94 GHz, 19.5 to 26 GHz, and 29.5 to 35 GHz with the peak gain of 16 dBi, 27.4 dBi and 30.9 dBi at three bands, respectively.

车联网三波段高增益共享孔径天线

车联网（IoV）的实现为智慧城市智能交通的发展提供支撑。现有和未来的无线网络允许车辆连接到地面基站（BS）、自主飞行器（AAV）和卫星网络，这是实现这一雄心勃勃的车联网目标的关键。无线行业和车辆领导者现在正在寻求天线创新，以支持sub-6 GHz（车辆到aav）， 24 GHz（车辆到bs）和20/30 GHz（车辆到卫星）网络的集成。本文介绍了一种新型三波段高增益天线，该天线首次产生了sub-6、K-和Ka波段的工作频率。在共享孔径配置下，通过混合6ghz以下的Fabry-Perot腔天线（FPCA）、k波段折叠反射天线（FRA）和ka波段反射天线（RA）实现了三波段性能。采用三种在不同频段具有不同功能的元原子（MAs）构成了所提出的共享孔径天线的三个功能元表面。为了演示，制作了一个原型并进行了测量。测量到的有效带宽（反射系数≤−10 dB，增益变化≤3 dB）分别为5.62 ~ 5.94 GHz、19.5 ~ 26 GHz和29.5 ~ 35 GHz，三个频段的峰值增益分别为16 dBi、27.4 dBi和30.9 dBi。

期刊介绍： The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
