5G microstrip antenna operating at millimeter band frequency

Abstract

The initial goal of this research was to correct the offset of the 5G microstrip antenna from 30 degrees to as close to 0 as possible. This was done by adding a U-Slot and miniaturizing the antenna to correct for frequency shift. After making changes, the offset of the antenna was able to be corrected to -5 degrees. While the values were still acceptable, the antenna did suffer a loss in both the return loss and the bandwidth compared to the original.
