Abstract
The present invention provides a microwave and millimeter wave circuit apparatus having a reduced size and which can be produced easily, improving productivity. The microwave and millimeter wave circuit apparatus includes: a grounding conductive layer 4 grounded; a first dielectric layer 5 formed on this grounding conductive layer 4; a signal line selectively formed on this first dielectric layer 5; a second dielectric layer 7 covering at least a portion of the signal line 6; a cavity 2 formed in this second dielectric layer 7 and extending to the signal line 6; a monolithic microwave integrated circuit 1 arranged in the cavity 2 and connected to the signal line 6; and an antenna connected to the signal line 6.
