METAMATERIAL-BASED ANTENNA AND GENERATION METHOD OF WORKING WAVELENGTH OF METAMATERIAL PANEL

摘要

The present invention relates to an antenna based on a metamaterial and a method for generating an operating wavelength of a metamaterial panel. The antenna comprises a radiation source, and a metamaterial panel capable of converging an electromagnetic wave and operating at a first wavelength. The metamaterial panel is adapted to convert the electromagnetic wave radiated from the radiation source into a plane wave and to enable the antenna to simultaneously operate at a second wavelength and a third wavelength which are smaller than the first wavelength and are different multiples of the first wavelength. The present invention further provides a method for generating an operating wavelength of a metamaterial panel for use in the aforesaid antenna, which comprises: acquiring a numerical value m3/m2 that is within a preset error range relative to a ratio λ3/λ2 of a third wavelength λ3 to a second wavelength λ2; calculating a lowest common multiple m1 of m2 and m3; and generating the operating wavelength λ1 of the metamaterial panel, which is represented as λ1=λ2(m1/m2) or λ1=λ3(m1/m3). By designing the operating wavelength of the metamaterial panel, the antenna is able to operate at different wavelengths simultaneously; and the electromagnetic wave from the radiation source can be converted into a plane wave. These improve the convergence performance and reduce the volume and size of the antenna.
