Abstract:Abstract. We introduce a new tunable reflectarray element for an
operation frequency of 26 GHz in the k-band. It is shown that a
340∘ continuous tunning range of the reflected wave can be
accomplished by using an aperture-coupled patch antenna with only one single
varactor diode. The simplified design and the small needed space make it
usable for k-band reflectarrays with many elements. The functionality of the
reflectarray element is explained and the crucial parts are analyzed. The
approach to get a full pha… Show more
