In this article, a planar antenna based on Fibonacci word fractal geometry with defected ground structure (DGS) has been investigated. A novel type of antenna radiator is proposed using Fibonacci word fractal which works for public safety and dedicated short range public safety applications. Size of proposed antenna is 50 × 44 mm and it resonates at 4.9 and 5.9 GHz having bandwidth ranging from 4.8 to 5.1 GHz and 5.8 to 6.8 GHz, respectively. Defected Ground Structure is used to improve gain for lower frequency band. Representative results of fractal patch antenna are reported to access the effectiveness of the developed approach in public safety applications. Simulation and experimental result confirms the efficiency of Whale Optimization Algorithm for antenna design. Experimentally measured results are matches well with simulated results and quite promising.
