PTFE Substrate (For HF Wave/MM Wave)

“PTFE substrates are used as high-frequency peripheral equipment parts such as antennas in high-frequency areas by their excellent dielectric characteristics and coefficient of water absorption.
In recent years, with the diversification of information in the telecommunications field, higher frequencies have been implemented in the radio waves used, and it has also become necessary for the antennas and circuit components used in information communication to adapt to higher frequencies.”
