AI Technical Summary
Existing car antennas are too long, which affects the appearance of vehicles and sales, and a long antenna length is required to receive low-frequency signals.
A low-frequency antenna assembly for automobiles was designed. By wrapping the signal receiving antenna around the outer surface of the signal receiving device to compress the antenna length, and installing the cover through the cooperation of the slot and the plate, combined with waterproof adhesive and wear-resistant pad, the aesthetics and signal receiving capability are improved.
While reducing antenna length, signal reception capability was maintained, vehicle appearance was improved, rainwater ingress and static electricity were prevented, and the lifespan of the device was extended.
