新型等离子体天线辐射特性的研究的开题报告 Title: Study on Radiation Characteristics of New Type Plasma Antenna Introduction: Plasma antennas have been studied for a long time. The high conductive ability and adjustable parameters of plasma make it capable of generating various radiation patterns. In recent years, a new type of plasma antenna has been proposed, which is different from traditional plasma antennas in terms of the plasma generation method and antenna structure. The new type of plasma antenna uses a dielectric gas discharge tube to generate plasma, and the antenna structure is composed of two parallel cylinders, which form a coaxial transmission line. The inner cylinder is used to generate plasma, and the outer cylinder acts as the radiating element. The new type of plasma antenna has the advantages of low cost, simple structure, and high radiation efficiency, which makes it a potential candidate for applications in communication, radar, and other fields. Objectives: The objective of this research is to investigate the radiation characteristics of the new type of plasma antenna. In particular, the research will focus on the following aspects: 1. Analysis of the electromagnetic field distribution and mode characteristics of the antenna structure. 2. Simulation and analysis of the radiation patterns of the new type plasma antenna. 3. Study of the effects of plasma parameters such as plasma density, gas flow rate, gas pressure, etc. on the antenna radiation performance. 4. Design and fabrication of the new type of plasma antenna, and experimental verification of the simulation results. Methodology: The research will be conducted in the following stages: 1. Theoretical analysis: Based on the principle of electromagnetic wave propagation and transmission line theory, the electromagnetic field distribution and mode characteristics of the new type plasma antenna will be analyzed. 2. Simulation: Using electromagnetic simulation tools, the radiation patterns and performance param
