射频传输线的设计及仿真 摘要 关键字：传输线理论 MATLAB计算机辅助计算 微带线特性阻抗仿真 RF Transmission Line Design and Simulation ABSTRACT Radio frequency (RF) said electromagnetic frequency can be radiation into space,the range of the frequency range from 300 KHZ to 300 GHZ,it is a kind of high frequency ac change electromagnetic waves.Transmission lines based on transverse electromagnetic (TEM) way to transmit power and (or) electrical signals of guided wave structures,the characteristics of the transmission line is horizontal size smaller than the wavelength of the work.The design of the RF transmission line is of great importance,transmission line design is a high frequency cable, RF microwave engineering, optical fiber communication and so on the basis of photoelectric engineering,in order to make energy can without loss of transmission in the communication network, a good design of a transmission line is critical. Along with the popularization and development of computer technology, the computer aided analysis and design in various engineering fields obtained widespread application and development. Problem of transmission lines with the help of a computer to assist in solving calculation, more accurate and fast. We use corresponding analytical formula of transmission line, the transmission line problem is compiled with MATLAB language of some of the program. Distribution circuit design method of impedance matching is the most important, it directly decides the circuit load to obtain the size of the signal power. Well be microstrip line impedance matching for the discussion of theory and simulation implementation.
