Abstract
Aspects of the disclosure provide an antenna system. The antenna system can include a dielectric substrate that has a top surface and a bottom surface covered by a ground plane, and four identical antenna elements symmetrically distributed on each corner of the bottom surface. Each antenna element can have a concentric-pentagonal-slot-based structure that is etched out of the ground plane, and includes an outer pentagonal slot and an inner pentagonal slot. Each side of the outer pentagonal slot can be parallel with a corresponding side of the inner pentagonal slot.
