Extra-broadband antennas are of great importance in broad spectrum applications, military and security. These antennas are essential because of their ability to cover multiple frequency bands in radar systems and electronic warfare environments. On the other hand, frequency jumping, lack of proper matching of radiation pattern and dimensions are considered as weaknesses and reduced efficiency in these systems. In this paper, a functional ultra-broadband antenna is designed and fed to improve the performance in wide spectrum systems using symmetric radiation and electromagnetic coupler system. The proposed model is presented with a homogeneous metamaterial line EBG structure and a modified combination model of miniature geometry and with good combination in terms of dimensions, bandwidth, gain and radiation pattern. The antenna is in the range of 1-7 GHz and the frequency of resonance is in the range of 4 GHz. The software used in ADS (2022.1.2) HFSS (15.3) and adapting the impedance and reducing the input losses in the proposed model have been designed. Finally، the results indicate that the proposed antenna is a simple and compact antenna that many of the approved standards for the upgrade of bell and radar systems Broad-spectrum systems such as bandwidth improvement, miniaturization, impedance matching and radiation pattern modification are the main goal of the project.
