Embodiment Construction

[0036] Please refer to Figure 1A to Figure 1C , Figure 1A and Figure 1B Are schematic diagrams of a first surface P1 and a second surface P2 of a radio frequency system 10 according to an embodiment of the present invention, and Figure 1C for Figure 1A A-A' line section in the middle. The radio frequency system 10 may be a microwave transceiver network of a radar system, such as an array antenna for a vehicle, but is not limited thereto. It includes a substrate 100, an antenna series AST_1 to AST_n, wires CN_1 to CN_n, a connector VT, and a first The radio frequency signal processing module 102 and a second radio frequency signal processing module 104. For clarity, Figure 1A and Figure 1B The four sides L1 to L4 of the substrate 100 are marked to distinguish the illustrated directions of the first surface P1 and the second surface P2. Such as Figure 1C As shown, the first surface P1 and the second surface P2 are respectively the upper and lower surfaces of the substrate 1...

Abstract

A radio frequency system. The radio frequency system includes: a substrate; a plurality of antenna series formed on the first surface of the substrate, each antenna series includes a plurality of radiators connected in series, and the plurality of antenna series are classified into first and second groups A group; a plurality of wires formed on the second surface of the substrate for transmitting radio frequency signals; a plurality of connectors disposed in the substrate for coupling the plurality of wires and the second group of antennas in the plurality of antenna series series; the first radio frequency signal processing module, coupled to the antenna series of the first group, used to send and receive radio frequency signals through the antenna series of the first group; and the second radio frequency signal processing module, coupled to a plurality of The wires are used to couple the antenna series of the second group through a plurality of wires and a plurality of connectors, so as to transmit and receive radio frequency signals through the antenna series of the second group. The invention can avoid false alarms caused by the reflection of objects higher than the horizontal plane, so as to improve system efficiency and system reliability, and can increase the functions of the vehicle radar system.

Description

Technical field [0001] The invention relates to a radio frequency system, in particular to a radio frequency system that can increase the transceiver function without greatly increasing the installation area. Background technique [0002] The array antenna is an antenna system composed of multiple identical antennas arranged according to a certain rule, and by adjusting the placement of antenna components in the array antenna, the array antenna can reach a specific radiation pattern, and the main beam can be concentrated in a specific direction for transmission signal. For example, for a vehicle radar system, the array antenna is usually set to perform two-dimensional detection in the horizontal direction. However, in practical applications, only the horizontal two-dimensional detection may be affected by reflections from objects above the horizontal plane (such as billboards, traffic signal signs, bridges, buildings, etc.). Due to hardware limitations, false alarms (FalseAlarm ...
