研究目的
Introducing a new family of fractal curves for miniaturizing microwave components, providing designers with the freedom to choose among form factor, design complexity, and achieved miniaturization.
研究成果
The proposed family of fractal curves offers a systematic approach to miniaturizing microwave components, with the flexibility to choose among form factor, design complexity, and miniaturization. The symmetry of the fractals ensures distortionless radiation patterns, and the study provides equations to predict resonant frequencies and quantify miniaturization effects.
研究不足
The complexity of fractal geometries increases with higher values of m and n, potentially limiting fabrication feasibility for very high iterations. The study focuses on monopole antennas, and the applicability to other microwave components may require further investigation.
1：Experimental Design and Method Selection:
The study involves the generation of a novel family of fractal curves characterized by two integer values m and n, where m determines the form factor and n the iteration number. The geometry of these fractals is governed by specific equations.
2：Sample Selection and Data Sources:
Printed monopole antennas are designed for various values of m and n to characterize the resonance properties.
3：List of Experimental Equipment and Materials:
Antennas are fabricated on commercially available FR4 substrate with specific properties.
4：Experimental Procedures and Operational Workflow:
Fractals are generated using a MATLAB program, and their coordinates are exported to HFSS for full wave analysis. Fabricated antennas are tested using an Agilent N5222A Vector Network Analyser.
5：Data Analysis Methods:
The results from simulations and experiments are analyzed to quantify the effect of fractals on reducing resonant frequency and to establish a saturation point for miniaturization.
