Abstract

In this work the concept of a Fresnel zone antenna for dual-band detection in the IR and millimeter wave region is presented. The design is based on a Fresnel zone plate lens in the IR that is transformed to serve as a millimeter-wave antenna. Two different designs are presented, a circular-zone design that gives a high diffractive efficiency in the IR and a square-zone design that gives a higher response in the millimeter band but a lower focusing efficiency in the IR. Both designs have an operation bandwidth with the same low frequency limit of 400 GHz ( 750 μ m ) , which can be tailored by changing the number of Fresnel zones, and a high frequency limit of 4.5 THz ( 65 μ m ) for the circular-zone design and 5 THz ( 59 μ m ) for the square-zone design.
