Patent number: 7501992Abstract: The planer antenna includes: a linear radiating antenna element to which electric power is to be supplied; and multiple linear parasitic antenna elements to which electric power is not to be supplied. The parasitic antenna elements are disposed at a position at which the radiating antenna element and the parasitic antenna elements cross each other without contact. The parasitic antenna elements lying in a direction in which the radiating antenna element and the parasitic antenna elements cross each other, and each of the crossing portions of said plural parasitic antenna elements, which portions cross said radiating antenna element, are bent in such a manner that the crossing portions of the parasitic antenna elements are in parallel with the radiating antenna element. Thus, it is possible to provide a planer antenna which can obtain a good circularly polarized wave with a simple construction. In addition, the planar antenna can be downsized.Type: GrantFiled: June 28, 2007Date of Patent: March 10, 2009Assignee: Fujitsu LimitedInventors: Takashi Yamagajo, Toru Maniwa, Andrey Andrenko
