Book Description:
Antenna gain is essential for microware communication, and since it helps both transmitting and receiving, it is doubly valuable. Practical microwave antennas provide high gain within the range of amateur favrication skill and budgets. Three type of microwave antennas meet there criteria: horns, lenses and dishes. Horns are simple, foolproof and easy to build; a 10-GHz from with 17 dB of gain fits in the palm of a hand. Metal-plate lenses are easy to build, light in weight and noncritical to adjust. Finally, dishes can provide extremely high gain; a 2-foot dish at 10-Ghz has more than 30 dB of gain, and much larger dishes are available.
In Chapter 1, some of the topics in the conventional circuit theory are reviewed, which have particular importance in the theory of microwave circuits. There include the theory of transmission line, bilinear transformations, and power waves. Chapter 2 gives a review of vector analysis and the fundamental properties of electromagnetic fields to facilitate our later study. In Chapter 3, waveguides are discussed for the first time. Here, the eigenvalue problem is studies in detail including the completeness of eigenfunctions. Without the discussion of the completeness, the theory is only partially correct since no answer is given to certain fundamental questions such as why an exponential variation with distance is assumed for each mode and no other pos...
The recent shift in focus from defense and government work to commercial wireless efforts has caused the job of the typical microwave engineer to change dramatically. The modern microwave and RF engineer is expected to know customer expectations, market trends, manufacturing technologies, and factory models to a degree that is unprecedented in the history of RF/microwave engineering. With a broad, balanced range of material, The RF and Microwave Handbook provides you with the means to understand and use these factors to improve your overall performance....
For MF-UHF Applications
Magnetic resonance imaging, semiconductor processing, and RFID are some of the critical applications within the medium frequency (MF) to ultrahigh frequency (UHF) range that require RF designers to have a solid understanding of analytical and experimental RF techniques. Designers need to be able to design components and devices cost effectively, and integrate them with high efficiency, minimal loss, and required power. Computer-aided design (CAD) tools also play an important part in helping to reduce costs and improve accuracy through optimization. RF Circuit Design Techniques for MF-UHF Applications explains how to design, simulate, and implement RF/microwave components and devices for applications within the medium frequency (MF) to ultrahigh frequ...
