Effects of plastic vehicular covers on radiation characteristics of lightweight, dual‐band antenna for vehicular communications

Abstract

This paper highlights the impact of curved and flat vehicular plastic parts on the radiation characteristics of two dual-band antennas for cellular -vehicle to everything (C-V2X) applications. The radiation patterns of the antennas are measured in SATIMO near field measurement system and are compared during the following setups: (a) antennas alone in the near field system, without the presence of a plastic part; (b) antennas mounted on the inside curved surface of a driver's side mirror cover; (c) antennas mounted on the outside curved surface of the driver's side mirror cover; (d) antennas mounted on a flat trunk lid; (e) antennas mounted on a curved plastic retrieved from the A-pillar of a vehicle. Comparison among the antennas radiation pattern measurements during these five different setups, results in the conclusion that the inside surface of the side mirror cover is the most suitable position to mount the presented dual-band antennas.

“…It is necessary to ensure the rationality of the ventilation system installa-tion. The installation of ventilation systems is quite complex, including the installation of air ducts, exhaust systems, and dust removal systems (Chletsou et al, 2022;Lavalle et al, 2022). Different equipment plays different roles, so it is necessary to constantly monitor the installation process of the equipment during the installation process to fully utilize its application functions.…”
