Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] In the microstrip antenna design, the key physical parameters affecting the microstrip antenna are the length L, width W and dielectric constant ε of the patch r . Under ideal conditions, the theoretically designed microstrip array antenna can meet the design requirements, but in actual production, due to the deviation of the processing technology, there will be errors in W and L. This scheme is to reduce the deviation caused by weighting. Impact. The logic block diagram of the whole invention content is as follows figure 1 shown.

Abstract

The invention relates to a design method of a Chebyshev microstrip array antenna. According to the method, model parameters comprise the width parameter W, length parameter L, and thickness parameterh of a microstrip antenna; the reasonable ranges of a dielectric constant and the thickness parameter h are set, and the distribution probability of the parameters within the ranges are analyzed according to actual situations; a plurality of groups of data are obtained, data analysis is performed on width deviation and length deviation in data analysis software on the basis of the obtained data; and the mathematical models of the deviation are obtained by means of data fitting. According to the design method of the above Chebyshev microstrip array antenna, data analysis is performed on the multi-element ideal Chebyshev antenna series-fed microstrip array antenna; when ideal data are utilized to design an engineering prototype, the deterioration of the parameters of the antenna caused by error caused by processing technologies and the randomness of plates can be avoided.

Description

technical field [0001] The invention relates to a Chebyshev microstrip array antenna, in particular to a design method of the Chebyshev microstrip array antenna. Background technique [0002] The Dolph-Chebyshev (Dolph-Chebyshev) polynomial array antenna uses a considerable power of the Dolph-Chebyshev polynomial to match the Fourier polynomial, so that it generates all sidelobe levels equal to the specified level (SLL) optimal range distribution. Its characteristics are: if the ratio R is given (that is, the sidelobe level is specified), the beam width of the first zero point is the narrowest; if the beam width is given, the ratio R is the largest (that is, the sidelobe level is the lowest); That is, there is an optimal sidelobe level and beam width design. Due to the convenience brought by this feature to the designer, the current array antenna is generally designed by Dolf Chebyshev polynomials. [0003] Microstrip antennas are favored by designers because of their sma...
