Abstract—This paper presents a new technique that resides on the use of electromagnetic bandgap (EBG) structures under a half-wave dipole antenna suitable for wireless communication systems. The implementation of the EBG electromagnetic band gap structures and superstrate creates a new frequency descent of half-wave dipole antenna of 73 ohms, simultaneously we are capable to operating at 2.6 and 3.5 GHz bands with only one antenna and also enhances its performance (gain, directivity), and improve the antenna efficiency. This is manifested by a very low dipole antenna return loss, besides improving the efficiency of the radiation pattern, by using the EBG structure in the proposed configuration. This technique also allows to the low profile antenna (26% reduction) contribution for cell phones. The dipole antenna initially operates at a frequency range of 3.5 GHz, but with the introduction of the EBG electromagnetic band gap structures, it resonates in two frequency of sub-6 GHz 5G bands 3.5 GHz and 2.6 GHz, which is well suited for 5G mobile applications. The design parameters of the antenna were optimized.
