Enhancement isolation antenna to multi-port for wireless communication

Abstract

Currently, there is a rapid increase in demand for the transmission of large amount of data with extreme accuracy, which is usually performed by the antenna system. Therefore, this work aims to design an antenna system that has the potential of improving the performance of such system in terms of reducing the antenna size, and expanding the bandwidth. First, a single-port antenna was designed after calculating the basic requirements and then a comprehensive analysis of the antenna performance was carried out to reach optimum performance. Then, the antenna was connected to two, three, and four ports. Such connection was implemented while maintaining efficiency and magnification in each case within the range for wireless applications. The antenna with four input ports was designed with a 45° angle on a circular circumference around the antenna to prevent interference between the ports. The modified antenna was designed to accommodate wireless communication applications (such as the 5G mobile communications network as well as the future 6G mobile communications network). The experimental results were compared with those obtained from the simulation studio Computer Simulation Technology, which is more compatible with the practical results.
