Substrate for high-frequency module and high-frequency module

摘要: A high-frequency module having a communication function is provided which uses circuit board including an organic substrate ( 5 ) formed from woven glass fabric 21 by weaving fibers 22 into mesh pattern and also material 20 integrally on the as core. The has distributed at close intervals of λe/4 (λe: effective wavelength signal) in traveling direction signal conductor patterns where resonant lines for transmission passive elements are formed. In module, “variations” dielectric constant etc. substrate, would be caused any thick thin distributions fibers, can reduced, thus conductive parts work with stable performances, respectively.
