Patent ID: 7501992

Claim:
A planar antenna, comprising: a linear radiating antenna element to which electric power is to be fed; and a plurality of linear parasitic antenna elements to which electric power is not to be fed, wherein said parasitic antenna elements are disposed at a position at which said linear radiating antenna element and said parasitic antenna elements cross each other without direct contact, said parasitic antenna elements lying in a direction in which said linear radiating antenna elements and said parasitic antenna elements cross each other, wherein each of the crossing portions of said plural parasitic antenna elements, which portions cross said linear radiating antenna element, are bent in such a manner that the crossing portions of said parasitic antenna elements are in parallel with said linear radiating antenna element, wherein said linear radiating antenna element is formed on one side of a dielectric substrate, and wherein said plural parasitic antenna elements are formed on the other side of the dielectric substrate.
