Abstract

A microstrip low-pass filter with the sharp rejection and wide stop band is presented. The circuit model is developed and analyzed based on traditional hi-lo impedance technique. Achieving the attenuation pole in vicinity of the desired -3dB point, magnetic coupling is added. For improving the design and miniaturization of the circuit, capacitance associated with shunt arm of the 3rd order low pass filter is explored. Comparison of proposed low pass filter has been done with existing filters in respect to effective structure as well as capacitive patch area. The filter design is simulated and dimensions are tuned to meet the desired frequency response. Ill. 7, bibl. 8 (in English; summaries in English, Russian and Lithuanian).
