Abstract:
An antenna-integrated microwave-millimeter wave module comprising:a dielectric substrate; a first conductor layer provided on said dielectric substrate and having a plurality of first holes formed therein to radiate electromagnetic waves; a first dielectric layer provided on said first conductor layer; an antenna feeding line provided on said first dielectric layer; a second dielectric layer provided on said antenna feeding line; a second conductor layer provided on said second dielectric layer and having a second hole formed therein; a third dielectric layer provided on said second conductor layer; a high-frequency circuit line provided on said third dielectric layer; and a semiconductor chip connected to said high-frequency circuit line and having a microwave or millimeter wave circuit formed, said first, second and third dielectric layers each having a thickness of &lgr;/4 or less, &lgr; representing wavelength of electromagnetic waves propagating through the dielectric layers, and said first, second and third dielectric layers having a relative dielectric constant of 10 or less.
