Book Description
A one-stop reference to the design and analysis of nonplanar microstrip structures. Owing to their conformal capability, nonplanar microstrip antennas and transmission lines have been intensely investigated over the past decade. Yet most of the accumulated research has been too scattered across the literature to be useful to scientists and engineers working on these curved structures. Now, antenna expert Kin-Lu Wong compiles and organizes the latest research results and other cutting-edge developments into an extensive survey of the characteristics of microstrip antennas mounted on canonical nonplanar surfaces. Demonstrating a variety of theoretical techniques and deducing the general characteristics of nonplanar microstrip antennas from calculated results, Wong thoroughly addresses the problems of cylindrical, spherical, and conical structures and gives readers powerful design and optimization tools. Up-to-date topics range from specific applications of spherical and conical microstrip arrays to the curvature effects on the analysis of cylindrical microstrip lines and coplanar waveguides. With 256 illustrations and an exhaustive list of references, Design of Nonplanar Microstrip Antennas and Transmission Lines is an indispensable guide for antenna designers in wireless and personal communications and in radar systems, and an invaluable reference for researchers and students interested in this important technology.
