Novel Dual-Band Dipole Antenna Integrated with EBG Electromagnetic Bandgap Structures Dedicated to Mobile Communications

摘要

In this paper, a half-wave dipole antenna based on electromagnetic band gap (EBG) structures is proposed for wireless communication systems (3.5 GHz, 2.6 GHz). The use of the EBG structure allows, on the one hand, to create a new frequency down of the 73 ohm half wave dipole antenna and on the other hand, to improve its performance (gain, directivity) and as well reduces its size around 26%. Initially the dipole antenna resonates around 3.5 GHz (WiMAX), and after the insertion of the electromagnetic bandgap structures EBG, the antenna operates in two frequency bands 3.5GHz and 2.6GHz, which is well adaptable to mobile communication applications. The antenna design parameters was optimized by the CST MW Studio software.
