Farfield antenna theory
WebIn this paper, the full-scale electromagnetic simulation model of the shared tower is established in FEKO software. Then, based on the multi-layer fast multipole theory and the generalized S-parameter theory, the far-field radiation pattern of the antenna and the expression of the coupling degree of the multiple antennas are given. WebAntenna Theory and Design, 3rd Edition Wiley This introduction to antenna theory and design is suitable for senior undergraduate and graduate courses on the subject. Its emphasis on both principles and design makes it perfect both as a college text and as a reference to the practicing engineer.
