Claim 1:
2. A wiring substrate for supplying radio frequency signals to an antenna module having a first antenna element and a second antenna element, the wiring substrate comprising:
a dielectric substrate having a laminated structure;
a first power supply wiring formed in the dielectric substrate and configured to supply a first radio frequency signal to the first antenna element;
a second power supply wiring formed in the dielectric substrate and configured to supply a second radio frequency signal to the second antenna element; and
a ground conductor formed in a layer that is different from both a first layer in which the first power supply wiring is formed and a second layer in which the second power supply wiring is formed,
wherein a hole portion is formed in the dielectric substrate from a first surface of the dielectric substrate between the first power supply wiring and the second power supply wiring toward the ground conductor,
wherein the hole portion extends from the surface of the dielectric substrate to the ground conductor,
wherein the dielectric substrate has a bent portion in which the first power supply wiring and the second power supply wiring are formed, and
wherein the hole portion is formed in the bent portion.
