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

摘要

The invention relates to a metamaterial-based antenna and a generation method of the working wavelength of a metamaterial panel. The antenna includes: a radiation source and a metamaterial panel having the function of converging electromagnetic waves and working on the first wavelength, the metamaterial panel being used to convert the electromagnetic waves emitted by the radiation source into plane waves and to allow the antenna to work simultaneously on the second wavelength and the third wavelength, said two wavelengths both being smaller than the first wavelength and being different multiples of the first wavelength. A generation method of the working wavelength of the metamaterial panel used for said antenna is also provided. The method includes: acquiring the numerical value m3/m2 that is in the preset error range of the ratio of the third wavelength and the second wavelength ?2/?3; computing the lowest common multiple m1 of m2 and m3; generating the working wavelength of the metamaterial panel, which can be expressed as: ?1=?2 (m1/m2) or ?1=?3 (m1/m3). The design of the working wavelength of the metamaterial panel allows the antenna to work on different wavelengths simultaneously and to convert electromagnetic waves of the radiation source to plane waves, thereby enhancing convergence performance and reducing the volume and the size of the antenna.
