研究目的
To propose a dual-polarized lens antenna system based on isotropic Huygens’ Surfaces for 12 GHz applications, achieving high isolation and gain over a wide bandwidth.
研究成果
The proposed dual-polarized lens antenna system achieves high isolation (>25 dB) and gain (>17.5 dB) over a wide bandwidth (11-13.5 GHz) through multimode resonance in an isotropic Huygens’ surface. Future work includes fabrication and experimental validation.
研究不足
The study is based on simulations only; no fabrication or measurements are conducted, which may not account for practical implementation issues. The design complexity of the single-type Huygens’ surface is high.
1：Experimental Design and Method Selection:
The study involves designing an isotropic Huygens’ surface lens with multimode resonances and combining it with a dual-polarized microstrip antenna as the feed. Full-wave simulations are used to analyze performance.
2：Sample Selection and Data Sources:
The unit cell and lens are designed with specific geometries; simulations are performed using periodic boundary conditions and full-wave electromagnetic simulation tools.
3：List of Experimental Equipment and Materials:
Substrate AD255C with relative permittivity εr = 2.55, thickness h/2 = 1 mm, metallic patches, and a dual-polarized slot patch antenna.
4：55, thickness h/2 = 1 mm, metallic patches, and a dual-polarized slot patch antenna.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: Design the unit cell with varying patch sizes to achieve phase shifts, simulate transmission properties, field distributions, and radiation patterns. Place the feed antenna at the focal point of the lens.
5：Data Analysis Methods:
Analyze S-parameters, electric field distributions, isolation, gain, and radiation patterns from simulation results.
