Abstract
This article presents techniques for the design of bandpass filter open-loop which is able to push the frequency 2f0 and 3f0. The circuit structure consists of a grid connected to a parallel-coupled line one-eighth wavelength long served as resonator connected the router to a variable electric field and the frequency response in artificial implant is placed in the center of the circuit. With the transmission line, a step at the input port and output as matching circuit when comparing the results of simulation and measurement results of the circuit at a frequency of 0.9 GHz. The result found that the presented circuit is able to reduce the frequency response of a false pseudo 1.8 and 2.7 GHz. for more than 30 and 19 decibels respectively.
