Embodiment 3

[0034] As a supplement to Embodiment 1 or 2: the human body capacitance induction formula: C=ε×A / d, when the relative permittivity ε is determined, the cross-sectional area A between the two metal surfaces of the capacitor and the gap between the two metal surfaces of the capacitor The change of the gap distance d leads to the change of the capacitance C. The human body itself carries current. When the human body is close to the antenna unit, an equivalent capacitance is formed, which will cause the capacitance value on the antenna to change. This change is captured by the capacitive sensor chip 3. , feedback to the MCU side, and issue countermeasures. The antenna feeding mode is pogopin feeding mode or RF line feeding mode.

[0035] The above term circuit board ground means the grounding of the circuit board. The above-mentioned vehicle anti-theft on-board antenna is installed in the on-board equipment. When the on-board equipment is in normal operation, when a human body is ...

Abstract

The invention relates to a vehicle anti-theft vehicle-mounted antenna which comprises an antenna unit, a matching circuit unit and a capacitive sensor chip. The capacitive sensor chip is arranged in the matching circuit unit, and the antenna unit is connected with the matching circuit unit. According to the vehicle anti-theft vehicle-mounted antenna disclosed by the invention, a vehicle can be prevented from being stolen without adding a complex circuit, an internal space of vehicle-mounted equipment is saved, and anti-theft measure cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle anti-theft, in particular to a vehicle anti-theft vehicle antenna. Background technique [0002] With the increasing popularity of automobile transportation in people's lives, the number and types of vehicles are increasing, and vehicle anti-theft technology is increasingly being valued by people. Resell stolen vehicles or dismantle car parts for retail sale. Vehicle anti-theft technology is increasingly advanced, and the theft methods of thieves are also increasingly sophisticated. [0003] Most of the existing vehicle anti-theft technology is to install on-board equipment, such as OBD, driving recorder, car locator, rearview mirror, etc. These in-vehicle devices are equipped with GPS positioning antennas to locate the vehicle position in real time, and then upload the vehicle position information to the owner through the network in the in-vehicle device to prevent the vehicle from being stolen...
