Vehicle communication system with adaptive antenna configurations
The patent US12027756B2 describes a versatile wireless communication system that integrates two antenna devices, each containing multiple antennas, and a switch to manage their connectivity. The system is designed to operate in two distinct modes: the first mode allows for a physical connection between the first and second antenna devices to facilitate a specific type of wireless communication, while the second mode decouples these devices, enabling a different communication system. The operational mode is determined by comparing the signal power received at both antenna devices. Notably, the first antenna device can be mounted on various vehicles, including trains, buses, and cars, and is capable of establishing a 2×2 communication link with stationary transceiver systems.
Further technical specifications include the ability to form a single effective antenna by combining antennas from both devices in the first mode, while the second mode can create multiple effective antennas. The design also emphasizes the spatial arrangement of antennas, with some separated by half a wavelength of the communication frequency, and the axes of the antenna devices being perpendicular to each other. The system supports cross-polarized communication and can coherently combine signals from the first mode, while signals in the second mode are uncorrelated. Additionally, the switch may function as part of a repeater, enhancing the system's flexibility and performance in various communication scenarios.
