A.K.Kureshiz Realization of microstrip band- pass filter. Parallel coupled microstrip filters are widely used in microwave circuits due to their insensitivity to fabrication tolerances, wide realizable bandwidth, and simple synthesis procedures.ġ. High-Performance microwave filters are essential circuits in many microwave systems where they serve to pass the wanted signals and suppress unwanted ones in the frequency domain. The basic third order bandpass filter as shown in figure 1. In modern communication systems, the size of the planar microwave filters is one of the major concerns. In case of planar microwave band-pass filters, there are four different types: the combline filters, the interdigital filters, the hairpin-line and the parallel coupled filters. Microwave band-pass filter plays an important role in the microwave systems especially in transmitting and receiving systems to identify and transmit the desired signals.

The advances of telecommunication technology arising hand in hand with the market demands and governmental regulations push the invention and development of new applications in wireless communication. Microstrip filter based on printed circuit board (PCB) offers the advantages as easy and cheap in mass production with different Dielectric constants.

The filter is designed and simulated in ADS (Agilents Advanced Design systems) software. The microstrip circuits has their own advantages compare to other microwave transmission like waveguide, coaxial cable, strip line as filter realized with wide bandwidth, compact size, easy to fabricate, good reliabilityĪnd reproducibility. The basic structure of Microstrip line consists of a conductive strip separated from ground plane by dielectric. Microstrip is a popular type of planar high frequency due to its ease of fabrication and its ability to integrate it with the other devices. Microstrip Band pass filters plays important role in all communication systems. Other band pass filters use no external source of power and consist only of passive components such as capacitors and inductors these are called passive band pass filters. Some band pass filters require an external source of power and employ active components such as transistors and integrated circuits, these are known as active band pass filters. Typical frequency response include low pass, high pass, band pass and band reject characteristics. A band pass filter is an electronic device or circuit that allows signals between two specific frequencies to pass, but that discriminates against signals at other frequencies and it can be formed by combining a low pass filter and a high pass filter.Ī filter is a two port network used to control the frequency response at a certain point in a system by providing transmission at frequencies within the pass band of the filter and attenuation in the stop band of the filter. At Microwave Frequencies the discrete components are replaced by transmission lines, for low power applications microstrip are used which provide cheaper and smaller solution of Band Pass Filter.

Those filters have wide application in modern wireless communication system.

Finally, the simulation is done using the Advanced Design System software and simulated on FR4 substrate as the dielectric material with the thickness ofġ.6 mm and the conductor thickness of 45 Âµm. The hairpin structure makes the filter structure more compact in size. A compact microstrip Hairpin line bandpass filter design is presented in this paper for a centre frequency of 2.4 GHz. In this project, the bandpass filter is designed using hairpin structure. A filter represent a class of electronic filter.
