ISBN: 0-471-19773-4

The major objective of this book is to present modern RF and microwave technology for wireless applications. Although wireless communication is a major application of RF and microwave technology, it also has extensive applications in radar, sensors, navigation, radio-frequency identification, remote sensing, surveillance, broadcast, smart automobiles and highways.

The book is intended to serve as a reference for practicing engineers and technicians working in the area of RF, microwaves, communications, solid-state devices and radar. It should also be useful as a textbook for RF and microwave courses designed for university students.

The book is organized into 12 chapters. Chapter 1 is an introduction and offers a brief history of the technology. Chapter 2 presents an account of some general wireless systems, including frequency allocations, cellular systems in the US, Europe and Japan, cordless telephony, wireless LANs, satellite communications and future wireless systems. Chapter 3 gives an overview of various active devices, such as Si bipolar transistors, GaAs MESFETs, hetero-junction FETs and HBTs, as well as microwave integrated circuit technologies commonly used in the construction of RF and microwave wireless systems. Chapter 4 describes the system parameters for a typical receiver and transmitter, including noise, dynamic range, intermodulation products and adjacent channel power ratio. Chapter 5 describes the transmission line characteristics of waveguides, coaxial lines, microstrip lines and other planar transmission lines, lumped elements and impedance matching techniques, and networks. Chapter 6 covers filters and couplers. Active or solid-state circuits such as switches, low noise amplifiers, mixers, frequency converters, oscillators, modulators and power amplifiers are presented in Chapters 7 to 11. Antennas and their operating principles are discussed in Chapter 12, including monopole and dipole antennas, loop antennas, horn antennas and microstrip patch antennas.

This book aims to detail various broadband microstrip antenna (MSA) configurations, collecting in one volume the information that is currently scattered around in various journals, conference proceedings and books. It explains concepts of several broadband techniques, providing suitable examples without getting into mathematical details.

The book is divided into nine chapters covering different aspects of MSAs. The main focus is on bandwidth-enhancement techniques but other important configurations are also discussed in detail. Chapter 1 introduces the MSA configuration and discusses its advantages, disadvantages and applications. Chapter 2 discusses the analysis and design of regularly shaped patches such as rectangular, circular, semicircular, triangular and annular-ring patches. Chapter 3 discusses the multi-resonator technique in a planar configuration, elaborating on the mechanism of gap, direct and hybrid coupling for broadband performance in rectangular, circular, semicircular and triangular microstrip patches. Chapter 4 describes multi-layer broadband configurations, presenting electromagnetic and aperture coupling mechanisms, and discussing a microstrip and coaxial feed for electro-magnetically coupled configurations. Chapter 5 presents stacked multi-resonators for broadband performance with increased gain, and discusses multi-resonator stacked rectangular and circular MSAs. Chapter 6 presents compact configurations using shorting posts, resistive loading and slots. Chapter 7 describes dual-frequency MSAs using higher order modes, stub loading, shorting posts, lumped elements and slots. Chapter 8 defines circular polarization (CP), dual- and single-feed CP, compact CP, and broadband CP MSAs and arrays. Chapter 9 details planar monopole antennas, which are variations of MSAs and clearly describes the analogy between planar monopole antennas and MSAs.
