F-J Antenna Structure Compact Size with Impedance Ratio 13:1 Excited by Tapered CPW

This research presented a novel of (F-J) antenna, where the tapered feeding strip line fed a frame that loops back to the ground. Within this frame, branches forming the structures F and J. The antenna has measured wide impedance bandwidth of 3.4-30 GHz that can be used for many wireless communications such as WiMAX (3.4GHz–3.6GHz /5GHz– 6GHz), Wi-Fi (5GHz–5.8GHz), 5G (5-6 and 27-28 GHz), ultra wideband (UWB) (3.1–10.6 GHz), and multichannel video and data distribution service (MVDDS) (12.2–12.7 GHz). . The effect of varying the dimensions of some parameters and the surface current distribution had been investigated carefully in this research to optimize the dimensions of the proposed antenna. A good matching was observed between the measured and the simulated data for the reflection coefficient, the radiation patterns and the gain.
