Abstract
Transmit-arrays (TAs) can be a cost-effective solution
for Satellite on-the-Move (SoTM) applications. Combining the
flexibility of TAs with 3D printing can further enhance the lowcost potential of these antennas. This work shows that Fuse
Deposition Modelling (FMD) 3D printing technique can be
effective even for demanding designs, as the one considered in
this study. A dielectric TA antenna with wide mechanical beam
scanning (up 50 degrees) with an extremely low profile
(F/D=0.34) and 26 dBi maximum gain at 30 GHz is optimized.
Although the resulting aperture is thicker and have higher losses
comparing with solutions based on printed circuit board (PCB)
technology, we show that the performance of this low-cost
antenna is still competitive. We study how different ways of
crafting the TA phase correction in the dielectric block can
improve the performance of the antenna.
