SUMMARY:

This work proposes the insertion of Complementary Split-ring Resonators (CSRR) in the planar filter ground. The intention is to improve some filter parameters found in the literature that have practical application, considering the growing demand for higher performance, smaller size, lower weight and cost of the devices that integrate the communication systems. The filters chosen were a bandpass filter that uses matrioska geometry for applications in the 2.45 GHz Industrial Scientific and Medical (ISM) band. The other filter was a low pass filter for digital TV applications. The idea is to insert the CSRR into the structure ground plane to increase the free attenuation of the matrioska band-reject filter and to reduce the size of the low-pass filter. In the work the numerical and experimental results are presented, for the purpose of validation of the proposed technique. A good agreement between the results is observed, these results show that the proposals presented were achieved.
