The Internet of vehicles (IoV) is an important part of mobile communication system with the development of Internet of things (IoT). A novel multiband automobile antenna is proposed, which can cover all frequency bands for the long-term evolution (LTE), the 5th generation wireless systems (5G), the wireless local area network (WLAN) and the dedicated short-range communication (DSRC) (from 690 MHz to 944 MHz and from 1.46 GHz to 6 GHz). The antenna is designed based on the monopole antenna, and the impedance matching performance of the antenna is improved by loading the toothed capacitor and the impedance matching disc. The simulation results show that the automobile antenna achieves good impedance matching in the working bandwidth and obtains omnidirectional radiation pattern in the horizontal direction. The electric field distribution of the antenna placed on the vehicle roof is simulated to evaluate the network performance of the antenna system in the urban environment. The transmission coefficient of the transceiver system using the automobile antenna is also analyzed based on the electromagnetic simulation results and statistical model. The blind area of mobile communication system is effectively covered with the automobile antenna, which could be used to connect the LTE cell and the IoV system.

A novel wideband cube resonator antenna (CRA) composed of metasurfaces is proposed in this letter, which can be applied to an active integrated antenna system. The resonant region of the CRA is formed by six metasurfaces of 4 × 4 arrays. The six surfaces can be equivalent to ideal electric walls. With the improved feeding slot, the dominant mode TE1δ1 and high‐order mode TE1δ3 are effectively excited, which enables a wideband and high gain performance for the CRA. A prototype of the antenna is fabricated and measured to verify the antenna design principle. The antenna has a measured impedance bandwidth of 17.0% (4.42–5.24 GHz) and a peak gain of 8.51 dBi, and good agreement between the simulated results and measured results is obtained. The proposed CRA shows resonant mode and radiation performance similar to those of traditional dielectric resonator antennas, which provides a new technique for the design of resonator cavity antennas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
