研究目的
To design and simulate a microstrip array antenna based on a new type of metamaterial structure to improve the antenna's gain, directivity, and overall transmission efficiency.
研究成果
The designed 2*2 supermaterial microstrip array antenna enhances the gain at the resonant point by nearly 6dB, improves the maximum gain of two-dimensional and three-dimensional patterns by about 2dB, and significantly improves directivity and reduces side lobes. It meets the requirements of microwave power transmission systems for antennas with high gain, low sidelobe, and good directivity.
研究不足
The study is based on simulation results using HFSS software, and real-world performance may vary due to manufacturing tolerances and environmental factors.
1：Experimental Design and Method Selection:
The study proposes a new metamaterial structure based on an open resonant ring and designs a microstrip array antenna using HFSS simulation software.
