Overview of Research on Broadband of Dipole Antenna

The methods of realizing broadband of dipole antenna are summarized and analyzed. Due to the narrow operating frequency band of the dipole antenna, in order to improve the bandwidth of the dipole antenna and improve its spectrum efficiency, the broadband of the dipole antenna is studied. This is also in line with the research trend of broadband antenna. This paper probes into the broadband methods of dipole antenna and analyzes the advantages and disadvantages of each method. It is pointed out that the core problem of broadband antenna is how to compromise the relationship between broadband antenna and other performance changes brought by broadband antenna. We propose that optimization algorithms can be used in antenna design to solve the problems caused by broadband antenna.
