دانلود کتاب Array and Phased Array Antenna Basics

This easy to read volume explains the principles of array and phased array antennas at an introductory level, without relying heavily on a thorough understanding of electromagnetics or even antenna theory. Although the principles are explained mathematically, the introduction is based on the array's physical characteristics rather than mathematics and is packed with first-hand practical experience. Array and Phased Array Antenna Basics provides an excellent introduction into the area that allows the reader to move onto specialist books on the topic with greater understanding. * Provides an introduction and practical approach to the principles of array and phased array antennas * Features a general introduction to antennas and explains the array antenna principle by discussing the physical characteristics rather than the theory * Progresses to a mathematically worked out explanation * Discusses topics usually unavailable in antenna textbooks, such as active element pattern, array feeding, means of phase changing, array antenna characterisation, sequential rotation techniques and reactively loaded arrays
