研究目的
To embed Chinese art into antenna design by creating character-shaped microstrip patch antennas for wireless communications and structural health monitoring, with a focus on achieving circular polarization and beam down-tilting.
研究成果
The Guo- and Meng-shaped patch antennas achieve beam tilting of 11° and 8° respectively in the yz-plane and a minimum axial ratio around 2.45 GHz after parameter tuning. This enables their use as artistic antennas for wall-mounted WLAN access points, combining performance with cultural artistry. Future applications could include hidden WiFi antennas in next-generation WLAN systems.
研究不足
The paper mentions a page limitation, indicating that not all parametric studies (e.g., for the Meng-shaped antenna) are fully detailed. The antennas are designed for specific applications like indoor WLAN, which may limit their use in other contexts. Optimization is based on simulation, and real-world performance might vary.
1：Experimental Design and Method Selection:
The study involves designing and optimizing two types of Kanji patch antennas (Guo-shaped and Meng-shaped) using computer-aided simulation (CST Microwave Studio) to achieve circular polarization and beam down-tilting. The L-probe feeding technique is employed for impedance matching and bandwidth enhancement.
2：Sample Selection and Data Sources:
Antennas are based on Chinese characters '国' (Guo) and '梦' (Meng), printed in SimHei font on a dielectric substrate. No specific datasets are mentioned; simulations are used for parametric studies.
3：List of Experimental Equipment and Materials:
Rogers laminate RO4003C substrate (εr=3.38, tanδ=0.0027, thickness 0.5 mm), nylon bolts for suspension, SMA connector, L-shaped feeding probe. Equipment includes CST Microwave Studio for simulation.
4：38, tanδ=0027, thickness 5 mm), nylon bolts for suspension, SMA connector, L-shaped feeding probe. Equipment includes CST Microwave Studio for simulation.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The patch is printed on the substrate, suspended over a ground plane at height H using nylon bolts, and fed via an L-probe connected to an SMA connector. Parameters such as cavity height (H) and feed location are varied and optimized through simulation to study effects on axial ratio, frequency, and beam tilting.
5：Data Analysis Methods:
Simulation results are analyzed to determine optimal parameters for return loss, efficiency, axial ratio, gain, and beam tilting angles. Data is presented in tables and figures for comparison.
