Abstract
The aim of this contribution is a new study on the achievement, fabrication and the test of a new low pass filter (LPF) coplanar structure based on periodic resonators. The proposed structure can be easly integrated with microwave devices, the validated LPF circuit has a wide band pass and high band stop. The design was done by two electromagnetic (EM) solvers one is based on moment method and the other one on finite integration technique. In order to reach a final LPF structure with good characteristics concerning the insertion loss of−0.8 dB and high attenuation until 15 GHz, the cut-off frequency of this filter is equal to 6,77 GHz. Many series of optimization were conducted using multiple algorithms. The whole area of the validated LPF is16×40 mm2.
