This report discusses the numerical analysis and evaluation of antenna characteristics of high-gain 3-dimensional (3D) printed reflectarray antenna for W-band millimeter-wave radar applications. The reflectarray antenna is advantageous in that it has a simple and flat structure. In addition, low-cost fabrication can be achieved using 3D printers. This study describes the fabrication of a 3D printed reflectarray antenna whose gain is more than 30 dBi in the W-band. First, the reflection signal phase of dielectric plates of different thickness are analyzed using finite-difference time-domain (FDTD) analysis to obtain the characteristics of the reflectarray design. Then, the eight-zone Fresnel reflectarray, in which each zone is separated by a phase difference of 45°, is analyzed and fabricated. The FDTD analysis result shows a 31.6 dBi antenna gain at 78.5 GHz. Finally, the designed reflectarray is fabricated using a commercially available 3D printer. The measurements indicate that a 30.4 dBi antenna gain is achieved, which is almost the same as the analyzed value at 78.5 GHz. |
