Slot Monopole Antenna

The top layer is for a 4 $\times$ 8 longitudinal slotted SIW array working in the Ku-band. Compared to a conventional SIW slot array just with a power divider, using the TE 20 mode provides the merits of not only reducing the number of vias but also relaxing fabrication limit and tolerance which could be the fabrication bottleneck at high frequencies.
