Özet
In this paper, the impact of the Defected Ground Structure (DGS) in PIFA antennas for IoT terminals is evaluated. Numerical analysis of antenna performance using finite element methods in term of gain and matching are discussed for Fishnet based PIFA antenna. The proposed PIFA antenna configuration is based on Fishnet Metamaterials etched in the ground layer using Defected Ground Structure (DGS) technique. The simulation results of the proposed Fishnet based PIFA antenna show dual band frequency at 3.9 GHz and 5 GHz with an enhancement in return loss, a slightly higher total efficiency of 92.50%, a gain and directivity enhancement of 3.11dB compare to the classical PIFA antenna gain.
