Design of Miniaturization Microstrip Filter in L-Band

Abstract:

A curve of the relationship between the gaps of microstrip resonator and coupling coefficients is presented in this paper, which based on the study of small planar microstrip bandpass filter design theory and implementation. According to the curve, a small microstrip bandpass filter with 6.67% relative bandwidth in L-band is designed by Multi-zigzag line and capacitive loading technology. Compared to the similar hairpin line filters, the area of the filter designed in this paper is reduced by 64% with advantage of smaller size and more simple structure. The examples and results of a fifth-order Chebyshev responsible L-band bandpass filter are presented in the end of this paper.
