DUAL BAND CIRCULARY POLARIZED ANTENNA BASED ON META-STRUCTURE AND METHOD FOR DESIGNING THE SAME

摘要

The present invention relates to a meta structure-based dual-band circularly polarized antenna and a design method thereof, wherein the dual-band circularly polarized antenna according to an embodiment includes a substrate having a ground plane having an asymmetrical cross-opening, and an asymmetrical cross-opening. It is formed, is formed to be spaced apart by a predetermined gap from the outer circumferential surface of the inner patch and the inner patch that implements the circular polarization characteristic of the first frequency band, and uses the difference in the resonance frequency using the asymmetry of the patch size. It may include an external patch implementing the circular polarization characteristic of the frequency band.
