Title:
アンテナ
Document Type and Number:
Japanese Patent JP4663705
Kind Code:
B2
Abstract:
An antenna for radiating an electromagnetic field includes a ground plane and a dielectric layer disposed on the ground plane. The dielectric layer has at least one exposed surface that radiates the electromagnetic field. The antenna includes at least one feeding element, such as a feeding strip or a feeding wire, that is disposed on one of the exposed surfaces of the dielectric layer. The feeding element electrically excites the dielectric layer. As such, the electromagnetic field radiates from the exposed surface and achieves a desired polarization radiation. Any exposed surface may radiate. Specifically, when multiple feeding elements are used, the exposed surface may radiate right hand circular polarization, left had circular polarization, and/or linear polarization.
