Nowadays, high frequency electronics are of great concern, especially in remote systems. With the rapid development of satellite communication, data items are developing towards fast and high frequency. As a result, a growing number of new projects need to continuously utilize HF substrates, satellite networks, cell phone reception base stations, etc. These communications projects must utilize HF PCBS. Using high frequency printed circuit board to transmit electromagnetic wave frequency of GHz, the loss can be negligible. Printed circuit boards with special properties are then used to transmit these electromagnetic waves. There are parameters to consider when planning a PCB for high-frequency applications. The expanding multifaceted nature of electronic components and switches requires faster signal flow rates and therefore higher transmission frequencies. Because of the short pulse rise time of electronic components, treating conductor widths as electronic segments also becomes critical for HF innovation. Depending on the parameters, the high-frequency signal is taken into account on the board, which means that the impedance (dynamic resistance) fluctuates in the transmitting segment. To prevent this capacitive effect, all parameters must be actually determined and executed at the highest level of the control program. Hf circuit board impedance is based on channel geometry, layer development, and the dielectric constant of the materials used.
