Microwave filters are vital component in wireless communication system.The use of microstrip technology in the design of microwave components and and integrated circuits has gained tremendous popularity since last decade because microstrip can operate in a wide range of frequencies.The book has been prepared for use as reference book for the undergraduate and post graduate Engineering Students.This book will be suitable for the students who are interested in the field of Microstrip Technology.This book serves all the Basic Requirement of the students who are doing their projects/thesis in Microstrip Filter.This book clearly explains the basic concepts and design methods of two types of Microstrip low pas filter i.e.,low pass filter with stubs,low pass filter with stepped impedance microstrip line, Wide band band stop filter using open circuited stubs and parallel coupled bandpass filter and Gap coupled band pass filter for wireless communication.The idea of Electromagnetic simulation software IE3D is also mentioned in this book.The application of matlab for filter design is also mentioned in this book.
