Ultra-thin microstrip antenna using metamaterial .

摘要

An antenna structure and a method of producing an antenna structure for wireless communications are disclosed. A radiating element of the antenna exhibits self similar structural properties for reduction in physical size and to improve antenna performance properties such as return loss and gain. To further reduce the energy loss and further increase the gain of the antenna, metamaterial resonating structures are disposed on the same plane as the radiating element of the antenna and on the same surface of a dielectric substrate. By disposing the metamaterial resonating structures on the same plane and on the same surface of the dielectric substrate as the radiating element, thickness of the overall antenna structure is minimized.
