Abstract

This Paper presents a methodology for the design of microwave band pass filter using square patch resonator. The 3D simulator ADS Momentum is used for the layout design. The performance of the filter is evaluated by method of momentum. This methodology figure out the design of dual mode filters using square resonator. The technique developed in this work results in filter with low loss, high power handling capability and good level of miniaturization. Dual mode filter is developed using square resonator presenting two poles in the pass band with centre frequency at 2.4 GHz and fractional bandwidth 13%. Maximum insertion loss of this filter is less than 1 dB and minimum return loss is 18 dB. The results show agood agreement with the study theory.
