A complete study and demonstration of a new stacked multilayer array using the Yagi concept were carried out in this work. The proposed design is based on several substrate stacked directly on each other, resulting in a very small footprint of the entire geometry. This configuration was demonstrated using two types of feeding techniques, showing the outstanding flexi- bility of the concept and suggesting its easy integration into mil- limeter-wave front-ends. The building elements and the 4  4 antenna array are analyzed, designed and measured. This offers the conception of a high gain antenna (19 dBi was reached) with compact size and minimal footprint. The measured results of S-parameters show a good bandwidth, a gain of 18 dBi, which are in very good agreement with the simulated results. The pro- totyped 4  4 array has a size of 28  24  2.4 mm  (including the distributed network feeding). Such a very small footprint leads to a far field around 16 cm at 60 GHz that allows a very close scanning unlike standard horn antenna.
