"Microwave filters are vital components in a huge variety of electronic systems, including mobile radio, satellite communications and radar. This is a thorough, graduate-level text which provides a single source for filter design including basic circuit theory, network synthesis and the design of a variety of microwave filter structures. The philosophy is to present design theories followed by specific examples with numerical simulations of the designs, with pictures of real devices wherever possible. The book is aimed at designers, engineers and researchers working in microwave electronics who need to design or specify filters."

"The ridge waveguide, which is a rectangular waveguide with one or more metal inserts (ridges), is an important transmission line in microwave engineering, now widely used in commercial electronics and communications devices. This book collects together much of the work of Professor Helszajn, an international authority in the field, and will enable the reader to have direct access to this important work without need for exhaustive search of research papers. Generously illustrated, it is likely to become the definitive reference source on this topic."

"ABSTRAKBand Pass Filter (BPF) memiliki peran penting dalam banyak aplikasi RadioFrekuensi (RF). BPF digunakan untuk memisahkan frekuensi yang berbeda. Hal inidisebabkan Spektrum elektromagnetik merupakan sumberdaya terbatas sehinggaharus dibagi. BPF digunakan untuk memilih sinyal RF dalam frekuensi kerjanya.Berbagai aplikasi komunikasi nirkabel terus muncul dan mengharapkan kinerja filterRF dengan kinerja yang tinggi dan ukuran yang lebih kecil. Proyek ini mempelajariprinsip mikro-strip bandpass RF filter. Metode yang digunakan Tangga dan Hairpin.Jenis Chebysev dengan orde 5 dan ripple sebesar 0,01 dB. Sistem ini disimulasikandalam software Desain Advanced System (ADS), kemudian di pabrikasi dan diukuruntuk memvalidasi desain. Tujuan penelitian ini adalah untuk merancang Microstripfilter bandpass untuk Automatic Dependent Surveilance Broadcast (ADS-B)dengan Frekuensi Pusat 1090 MHz menggunakan Ladder dan Metode Hairpin dankemudian membandingkan kedua metode untuk memperoleh kinerja yang lebihtinggi dan ukuran yang lebih kecil.

ABSTRACTBand Pass Filters has an important role in many Radio Frequency (RF) applications.They are used to separate different frequencies. The electromagnetic spectrum islimited and has to be shared; filters are used to select the RF signals within assignedspectral limits. Emerging applications such as wireless communications continue tochallenge RF filters with ever more stringent requirements—higher performance andsmaller size. This project studied the principle of micro-strip RF bandpass filter. Themethod used the Ladder and Hairpin. The Chebysev type with order 5 and ripple of0.01 dB was used. The system is simulated in software Advanced Design System(ADS), fabricated and measured for validate the design. The objectives are todesign Micro-strip bandpass filter for Automatic Dependent Surveilance Broadcast(ADS-B) with Frequency Center 1090 MHz using Ladder and Hairpin Method andthen compare the both methods for obtain higher performance and smaller size."

"This textbook introduces basic concepts and methods and the associated mathematical and computational tools employed in electronic filter theory, synthesis and design. "
