Abstract :
The influence of lumped capacitance connected between opposite ends of microstrip resonator strip conductor on frequency of transmission zero near to resonator natural frequency is investigated. It is shown that the design of hybrid filter based on such resonator allows to form transmission zeroes at required frequencies. The filter central frequency and fractional bandwidth is invariable. It allows to provide highest dumping at fixed frequencies and control slopes steepness of filter frequency response
