This work focuses on the design and simulation of a novel low-profile ultra-wideband antenna that combines the feature of vertical stacking with wing structure similar to bow-tie antennas. Additionally, it investigates the effectiveness of vertical stacking and discusses its optimization.

To gauge the effectiveness of stacking, we have compared the non-stacked, single-stack, double-stack, and triple-stack models against an optimizer function that covers parameters such as normalized cost, normalized return loss, and normalized -10dB bandwidth.

This optimizer function concludes that the single-stack model performs best compared to other models.

The antenna geometry is simulated and optimized using Altair FEKO. The proposed design of the single-stack model achieves a -10dB return loss over 248-752 MHz with VSWR < 2 and a relatively constant omnidirectional radiation pattern.
