Abstract

Filters are essential to the operation of this technology. There are various topologies to implement microstrip bandpass filters such as end-coupled~ parallel coupled, hairpin, interdigital and combline filters. This thesis discusses design, simulation, analysis, fabrication and testing of a Interdigital band pass filter by using microstrip technology. There is several application of a bandpass filter, for example it is used at the output of the oscillator to take out the required frequency or at the input of the receiver and the amplifier to pass the required frequency. In this report, the choice of Interdigital filter topology is discussed and this filter is designed at center frequency of 2.4GHz. This frequency is presenting for wireless LAN application and operates in the ISM (Industrial, Scientific and Medical) band which is covering from 2.4 GHz to 2.4835GHz. There are several steps to design this filter that are including by determine filter specifications, order of filter, low pass filter prototype elements, low pass to band pass transformation, physical dimension (width, spacing, length) and wavelength guide. The EM simulation of the filter design was completed on Microwave Office software and fabricated on FR4 substrate by using etching process. The explanation details for design procedure, simulated results, methods and techniques are discussed in this report.
