Abstract:
One of the important elements in microwave technology is the use of microstrip filters. In telecom circuits, filters are doing two important functions: Noise-canceling and separating different frequency bands.This filter is designed by using different geometric shapes on electric substrate. In this paper filter is designed with a T-shaped resonator. The resonator elements are important in determining the cutoff frequency on filter. In this paper we used the T shaped resonator because this resonator has a good sharp response in the transition band.The proposed filter has a wide bandwidth of 4.7 GHz to 27.6 GHz also the return-loss and insertion loss are more than 20 db and <0.2db and in the transition band filter has a good response and the size of filter only 0.076*0.074
