Abstract: This paper proposes analysis and stimulation of hairpin line microstrip band pass filter with the assistance of Hyper Lynx 3D EM software. Chebyshev low pass prototype with a pass band ripple of 0.1 db is chosen. The filter provides narrow bandwidth, high selectivity and compact size. The filter is designed to operate at centre frequency of 2 GHz; this frequency is used for wireless applications as most of them are below 3 GHz. In this paper various order of filters (3, 5,7) are designed and compared.
