A band pass filter based UWB which uses cascaded configuration of microstrip couplings is designed. Existing systems are not concentrating on the UWB design employing sufficient spacing so that they can reduce the unwanted signal reception. There is a need of a technique that enables the design of a planar UWB band pass microstrip filter with less than 1-dB insertion loss across its passband from 3. 1 to 10. 6 GHz, a wide upper stopband so that a reasonable spacing between the coupled lines will be achieved. We will be showing the performance in terms of E-H plane variation, beam pattern, S-parameter model and antenna calculated dimensions. The entire antenna is designed based on 2. 6 GHz. The parameters of the antenna are calculated by using MATLAB in this project.
