Ronold W. P. King is the Gordon McKay Professor of Applied Physics, Emeritus at Harvard University, USA. Since joining the Harvard faculty in 1938, he has supervised the research of over 100 Ph.D. students. He is a Life Fellow of the IEEE; a Fellow of the American Physical Society; and a member of the Bavarian Academy of Sciences and the American Academy of Arts and Sciences. He holds the Distinguished Service Award from the University of Wisconsin (1973), the Centennial Medal of the IEEE (1985), the Harold Pender Award from the University of Pennsylvania (1986), the Distinguished Achievement Award of the IEEE Antennas and Propagation Society (1991), and the IEEE Graduate Teaching Award (1997).
Cylindrical arrays lie at the heart of the antenna systems of most major radio communication systems, including broadcasting networks, cellular phone systems and radar. Here, the authors present practical theoretical methods for determining current distributions, input admittances and field patterns of a wide variety of cylindrical antennas. Key chapters cover analysis of horizontal antennas over, on and in the earth and sea; large resonant arrays of electrically short dipoles; and the theory and techniques of experimental measurement. Written by three of the leading engineers in the field, this reference is based on research carried out at Harvard over the last 40 years.
Preface; 1. Introduction; 2. An approximate analysis of the cylindrical antenna; 3. The two-element array; 4. The circular array; 5. The circuit and radiating properties of curtain arrays; 6. Arrays with unequal elements: parasitic and log-periodic antennas; 7. Planar and three-dimensional arrays; 8. Vertical dipoles on and over the earth or sea; 9. Dipoles parallel to the plane boundaries of layered regions; horizontal dipole over, on, and in the earth or sea; 10. Application of the two-term theory to general arrays of parallel non-staggered elements; 11. Resonances in large circular arrays of perfectly conducting dipoles; 12. Resonances in large circular arrays of highly conducting dipoles; 13. Direct numerical methods: a detailed discussion; 14. Techniques and theory of measurements; Appendices; References; List of symbols; Index.
