Abstract：In order to realize the miniaturization of filter,a complementary split ring resonator (CSRRs)is loaded on the upper-surface of substrate integrated waveguide (SIW)and half-mode substrate integrated waveguide (HMSIW)to reduce the original cutoff frequency.This paper analyzes the influence of parame-ter variation and element number of CSRR on the transmition performance so as to design novel miniature filters of SIW and HMSIW integrated CSRRs.The measurements show that the relative bandwidth of HMSIW filter is more than three times as wide as that of CSRR-SIW filter,i.e.about 10.24%,and the ef-fective circuit area of it is only 31.8×11.3mm2,i.e.about half of that of CSRR-SIW filter.The result shows that the designed filters are effective,and these two kinds of filters can be widely used in microwave and millimeter-wave systems.
