Abstract

This paper presents a new approach of designing a bandpass filter by applying a combination of microstrip and cylindrical dielectric resonators for X-Band application. Three dielectric resonators with a same permittivity and diameter of 60 and 5 mm respectively are applied in the circuit in order to obtain a wideband of more than 1.0 GHz. The combinations able to increase the coupling effect as well as minimizing the insertion loss in passband of the filter. An analysis on the effect of the width of the microstrip transmission line on the filter has been investigated in order to obtain the best response from the design. In order to prove that the new approach contributes more advantages and valuable at the desired application band, the return and insertion losses of the filter were deeply analyzed.
