Abstract
A circuit board with reduced dielectric losses enabling the movement of high frequency signals includes an inner circuit board and two outer circuit boards. The inner circuit board includes a first conductor layer and a first substrate layer. The first conductor layer includes a signal line and two ground lines on both sides of the signal line. The first substrate layer covers a side of the first conductor layer and defines first through holes which expose the signal line. Each outer circuit board includes a second substrate layer and a second conductor layer. The second substrate layer abuts the inner circuit board and defines second through holes which are not aligned with the first through holes, partially surrounding the signal line with air which has a very low dielectric constant. A method for manufacturing the high-frequency circuit board is also disclosed.
