Description

technical field [0001] The invention relates to the field of antenna design, in particular to a wide-band planar reflective antenna and an optimal design method based on a differential evolution algorithm. Background technique [0002] At present, antenna design mainly relies on manual work. When designing a new antenna, antenna design engineers often use electromagnetic theory knowledge combined with their own experience to design the antenna structure type that may meet the requirements according to the design requirements. Part of the parameters are optimized, and the optimization process is often a trial-and-error optimization in a local range. This design method has the following defects: 1. Antenna designers are required to have solid electromagnetic theory knowledge and rich antenna design experience, which requires relatively high requirements for antenna design practitioners; 2. This antenna design method is inefficient , need to consume a lot of material and finan...

This design method has the following defects: 1. Antenna designers are required to have solid electromagnetic theory knowledge and rich antenna design experience, which requires relatively high requirements for antenna design practitioners; 2. This antenna design method is inefficient , requiring a large amount of material and financial resources

At present, the performance of the broadband flat reflective antennas used in the prior art is poor, and the standing wave ratio is very large. Therefore, it is necessary to provide a design optimization method to design the parameters of the broadband flat reflective antennas, and at the same time provide a relatively low standing wave broadband planar reflector antenna
