AI Technical Summary

Problems solved by technology

Although relevant research has been carried out in China, their research objects are all passive interlayer microstrip antennas, and there is no research on the design method of active interlayer microstrip antennas to achieve optimal structural and electromagnetic comprehensive performance.

[0008] The above technical solutions have the following deficiencies: 1) Although the above studies have found that factors such as the service environment, honeycomb, panel, bonding, and dielectric materials will affect the electromechanical performance of the sandwich antenna, they have not established the mathematics of the influence of these factors on the electrical performance of the antenna. model, leading to inability to obtain optimal structural and electromagnetic synthesis results at the initial design stage

2) The existing literature lacks the design method of active sandwich microstrip antenna structure and electromagnetic synthesis. At present, the integrated method of electromechanical separation is usually used in engineering, that is, according to the electrical performance index, the radiation unit is designed by using antenna synthesis technology and mechanical principles respectively. The excitation current and the geometric size, shape and topology of the structure, etc., and then respectively check the strength of the antenna structure and the electrical performance of the antenna. This combination of electromechanical separation is difficult to ensure that the designed sandwich microstrip antenna meets the optimal overall performance.

3) Because this type of antenna has high integration, non-uniformity of materials and multi-discipline, the existing technology first uses electromechanical separation design method, and then achieves the desired electromechanical performance through sample debugging. Empirical design methods lead to long product development cycles, low yields, and high costs, and cannot obtain optimal structure and electromagnetic properties to meet engineering practical needs
