Passive planar transmit-array microstrip lens for microwave purpose

A complete transmit-array lens device at 12 GHz, for microwave purpose, is offered in this manuscript.In this document, an overview of the functioning of this kind of devices is given and the proposed transmit-array lens is thoroughly studied, with architecture discussion and selection, as well as the design, manufacturing, and validation of all the constituting elements of the lens (radiating elements, transmission circuits, and transitions). Eventually, a complete prototype of transmit-array lens is assembled and radiation pattern measurements in anechoic chamber, as well as gain and directivity values, are offered. © 2010 Wiley Periodicals, Inc.
