In this work, a novel broadband circularly polarized spidron fractal slot antenna has been considered. The design and implementation of single Spidron antenna, arrays of 2 × 2 and 4 × 4 are considered along with 4 × 4 array with the modified ground has been considered. HFSS13.0 has been used for the design and simulation, and fabrication FR4 epoxy material has been used. The broadband characteristics are examined simulation, and experimental results were presented. Theoretically a 4 × 4 array antenna offers the gain of is 5 dB and wide band ranging from 12.17 to 14.98 GHz. Its bandwidth is 2813 MHz. Practically a 4 × 4 array antenna operates from 9.9 to 14 GHz. The grid Spidron array performance evolution and comparison with 2 × 2 and 4 × 4 arrays is presented.
