|1. (WO2018201675) RESONANCE MODE ANALYSIS METHOD FOR DUAL-FREQUENCY SLOT ANTENNA|
|Applicants:||X-TRIP INFORMATION TECHNOLOGIES CO., LTD
|Title:||RESONANCE MODE ANALYSIS METHOD FOR DUAL-FREQUENCY SLOT ANTENNA|
Disclosed in the present invention are a resonance mode analysis method for a dual-frequency slot antenna. The dual-frequency slot antenna comprises a multi-mode slot resonator. The multi-mode slot resonator consists of a folded slot resonator and a co-planar waveguide stepped impedance resonator. The multi-mode slot resonator has a structure having reflectional symmetry with respect to a symmetry axis. The resonance mode analysis method for a dual-frequency slot antenna of the present invention is based on the even and odd mode concept, and enables acquisition of the resonance frequency and resonance order of each resonance mode of the dual-frequency slot antenna by means of analyzing electric field distribution of a multi-mode slot resonator in the dual-frequency slot antenna. In addition, the dual-frequency slot antenna of the present invention has a small design size, simple manufacturing process, and low cost, and has a power feed to a multi-mode slot resonator via a co-planar waveguide, thereby achieving a dual-frequency function thereof.
