Abstract: In this paper, a filter is proposed using micro strip, series of patch. S-parameters, return loss and VSWR are calculated for the filter. A reference filter is designed using a series of patches and is modified into an inverted L and J line filter (proposed filter). The proposed filter can be easily implemented and has excellent filter characteristics which are near to the ideal filter. There are many practical applications of this filter for example in microwave radio relay communication systems, radio astronomy, RADAR. The entire simulation is done using CST Microwave Studio.
