In this work the focus is on the impact of edge effects in the equilateral triangular lattice of a strongly coupled dipole antenna array. A novel wideband strongly coupled, single polarized, dipole element is designed and studied in a triangular grid. The antenna element operates in 6 : 1 bandwidth ratio. Our analysis for the edge effects is based the finite × infinite approach with multiple rows taken into account in order to capture the effects on the different edges that appear in triangular grids. The effects at the E-edge are studied as it is the plane where the currents are truncated. At the E-edge the variation on the behavior is mainly due to lack of closely coupling fields. Using the finite × infinite approach the variations along the E- edge of the array are studied for both rectangular and triangular grid. Finally, periodic resistive loading was used on the dipoles to dissipate the waves produced from the edges and smooth the impedance behavior along the array row.
