Design, Fabrication and Measurement of FOWLP-based Series-Fed Antennas for 6G D-Band MIMO Applications

In this paper, the development of FOWLP-based antenna arrays for 6G D-Band MIMO applications is presented. The proposed array consists of five patch elements, which are connected to each other to create a 1x5 series fed antenna array. The array was designed, simulated and fabricated on 150 μm mold substrate material at 140 GHz. The amplitude tapering method was applied to the array to suppress the high side-lobes levels. Finally, return loss and radiation patterns radiation of the proposed antenna array were measured and compared with simulated results. Very good correlation between simulation and measurement is obtained.
