研究目的
To propose a new frequency reconfigurable CSIW slot leaky-wave antenna using liquid crystal as medium at Ku band, aiming to achieve a wider bandwidth and larger tunable range.
研究成果
The proposed frequency reconfigurable CSIW slot leaky-wave antenna using liquid crystal demonstrates good reconfigurability with a tunable range of 1.5GHz and a maximum gain of 8.79dB. The antenna's design and performance suggest potential applications in satellite communications.
研究不足
The study focuses on the Ku band and uses specific materials (Rogers 5880 substrates and BOE-F028B liquid crystal), which may limit its applicability to other frequency bands or with different materials.
1：Experimental Design and Method Selection:
The antenna design is based on liquid crystal anisotropy characteristics, adopting comb shape and defected ground structure.
2：Sample Selection and Data Sources:
The antenna is simulated using HFSS
3：0 electromagnetic simulation software. List of Experimental Equipment and Materials:
Rogers 5880 substrates and type BOE-F028B liquid crystal produced by BaYi Space company are used.
4：Experimental Procedures and Operational Workflow:
The antenna's performance is evaluated by changing the liquid crystal’s permittivity.
5：Data Analysis Methods:
The antenna's return loss, VSWR, and radiation pattern are analyzed to verify its reconfigurability.
