研究目的
To design a two-dimensional (2D) periodic leaky-wave antenna (P-LWA) capable of oblique frequency scanning, allowing independent scanning in two distinct planes using opposite ports and achieving linearly-polarized pencil beams.
研究成果
The 2D P-LWA design successfully achieves oblique-plane frequency scanning with linearly-polarized pencil beams, validated through full-wave simulation. The antenna's four ports enable orthogonal planes scanning, offering potential for various applications.
研究不足
The design faces challenges such as high S21, indicating undesired transmission, and the open-stop band problem at the center frequency, which affects matching and Bloch impedance.
1：Experimental Design and Method Selection:
The design combines conventional 1D P-LWA unit cells and a periodic series feeding network tailored for frequency scanning in oblique planes.
2：Sample Selection and Data Sources:
The antenna consists of an array of 1D P-LWAs terminated by a series feeding line.
3：List of Experimental Equipment and Materials:
The structure is supported on Rogers 4350 and 4450F laminates.
4：Experimental Procedures and Operational Workflow:
The design is validated via full-wave simulation for single and two port excitations.
5：Data Analysis Methods:
The radiation pattern and scanning capability are analyzed using array factor theory.
