Antennas represent a critical technology in any of these wireless systems. Not only do they directly affect the received power of the system, they are alsotypically the largest and most visible part. Recently, the need for low-cost,low-profile, and lightweight antenna in the frequency range of the microwave/millimeter wave/THz band has regained momentum. "Basic Principles of Fresnel Antenna Arrays" provides us a with the basics of the various Fresnel Antenna approaches, in order to achieve low-cost, low-profile, and lightweight antenna in the microwave/millimeter wave band. A potential solution of the antenna problem lies in using lens technology in an array. The Fresnel zone plate lens (FZPL) antenna is in particular an interesting candidate for the array element. The limiting focusing properties of FZPL including subwave length focus are described in detail. The book further presents a novel hexagonal FZPL antenna which can be more effectively packed in an array due to its shape. Presents novelresults that have never been publishes Shows hot to produce and cheap and highly efficient antenna arrays INDICE: Introduction.- Fresnel Lens Technology.- Basic Research.- Diffractive Lens Antenna Array.
