The F4B Antenna PCB includes a core board provided with a hollow groove and a copper-clad plate adhered to the upper and lower surfaces of the core board by flow glue, and edges of the upper and lower openings of the hollow groove are provided with ribs.The following is about Antenna circuit board related, I hope to help you better understand Antenna circuit board.
The harmonic frequency of the signal edge is higher than the frequency of the signal itself, which is the unintended result of the signal transmission caused by the rapidly changing rising and falling edges (or signal jumps) of the signal. Therefore, it is generally agreed that if the line propagation delay is greater than the rise time of the 1/2 digital signal drive terminal, such signals are considered to be high-speed signals and produce transmission line effects.
