PROBLEM TO BE SOLVED: To provide a compact multilayer transmission line plate and an antenna module, while suppressing the manufacturing cost and transmission loss.SOLUTION: In a multilayer transmission line plate for use in a microwave band, a first conductor layer 11, a first dielectric layer 21, a second conductor layer 12, a second dielectric layer 22, and a third conductor layer 13 are laminated in this order to constitute a multilayer plate. The second conductor layer 12 forms a microstrip line becoming a feeder, and a patch conductor is formed on the third conductor layer 13. When the plane of the multilayer plate is viewed from above or below, the third conductor layer 13 on which the patch conductor is formed is arranged to partially overlap the second conductor layer. |
