Application Status of Left and Right Handed Transmission Lines in Broadband Antenna Units

摘要

In recent years, high standards and strict requirements have been put forward on the structure and performance of antennas, especially bandwidth, gain and directivity have become the most important performance indicators of antennas. How to broaden bandwidth has become a hot topic. The left and right hand transmission line structure has the advantages of low loss, frequency bandwidth, small size and easy fabrication, and is more suitable for the design of a wideband antenna. This paper summarizes the application of the left and right hand transmission lines in the broadband antenna unit.
