Hairpin filter is one of the most popular microwave frequency filters because of it is compact and does not require grounding. The filter is designed at center frequency of 2.44GHz with a fractional bandwidth of 3.45%. This frequency is presenting for wireless LAN application and operates in the ISM band (Industrial, Scientific and Medical) application. There are several step to design this filter that including by determine filter specification, order of filter, low pass filter prototype elements, low pass to band pass transformation, physical dimension (width, spacing and length) and wavelength guide.
