“…The installation position of the antenna in the car has a great impact on the function of the antenna, especially the radiation pattern. Therefore, the standard deviation is regarded as the second index to evaluate the radiation pattern [5]:…”

For the vehicle antenna measurement mounting on a vehicle, the offset mounting of the antenna will increase the maximum spherical wave expansion modes, with the increasing calculation time and the increasing risk of introducing environmental reflection noise. Therefore, basing on the matrix form of the traditional spherical wave expansion (TSWE) algorithm, this paper introduces the offset spherical wave expansion (OSWE) algorithm of the offset mounting antenna under test (AUT) aiming to decrease the maximum modes, shorten the calculation time and reduce the environmental noise with the method of spherical wave expansion. Taking LTE antenna and GPS antenna as examples, this paper analyzes the improved performance of OSWE algorithm comparing with TSWE algorithm on the vehicle antenna mounting on a vehicle, as well as the parameters like equivalent noise level (ENL), omnidirectional standard deviation (σ).

“…The Electronically Switched Parasitic Array Radiator (ESPAR) antenna is implemented on the rigid RO4725-JXR substrate and tested behind a mirror cover in the lab. In [6] the authors investigate the effect of the antenna position on its radiation. An antenna operating at 700, 2600 and 5870 MHz was mounted on different positions on a vehicle's rooftop.…”

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.

“…Common effects include diffraction, reflection, surface waves, re-radiation from induced currents and shadowing. Nevertheless, several studies compared antenna positions on cars [20], [21]. Reference [20] investigated performance based on data rates achieved in ray tracing simulations and identified the side mirrors, roof, A-pillars and the area above the windshield as promising positions.…”

Automotive Antenna Roof for Cooperative Connected Driving

et al. 2019

An automotive concept for vehicular communications is proposed that utilizes the potential of the roof area for antennas. Antennas are distributed in cavities and on shelves in the center and on the front and rear roof ends. The arrangement of antennas on the roof allows better radiation to the front and back of automobiles than shark-fins and single cavities. Combining several modules provides space for further antennas, sensors, and integrated front-ends, as well as better spatial separation for multiple-input multiple-output (MIMO) arrays beyond 5G, and cooperative connected and automated driving. A prototype was developed and built into a car chassis. The measured data were analyzed and evaluated in the view of coverage for vulnerable road users and on correlation for the MIMO.
