Abstract
In this report, the implementation and characterization of a millimeter wave Active Integrated Antenna Array is demonstrated, utilizing second harmonics for the MMIC oscillator with the multiple 3D printed PBG structure by etching. The 3D PBG structure is laminated by 2D PBG structure. The PBG was designed by computer program based on the FDTD method. The PBG structure works to suppress the leaked fundamental wave and makes improve performance of the Active Integrated Antenna Array.
