Claim 5:
6. 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 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.
