摘要

A slotted waveguide antenna array that is fabricated using electroplated 3D printed plastic is demonstrated. The waveguide antenna array is fabricated in three separate pieces and snapped together using a Lego-like process. The waveguide center feed is directly printed with the back cavity which simplifies the process and makes it robust. Measurement results show a 2x4 slot array in good agreement with simulation results. Measured return loss and gain at 7.7 GHz are -15 dB and 15.86 dBi, respectively. In this design, the waveguide is directly printed with the back cavity which simplifies the process and makes it robust.
