Abstract: The objective of this work is the design and simulation of an antenna based on metamaterials in order to miniaturize the dimensions of planar antennas. Metamaterials have been on the rise in recent years. The new properties make it possible to envisage the realization of new electronic components with new functions. Metamaterials are artificial materials designed for different telecommunications applications in order to improve the performance of antennas in terms of efficiency, compactness and miniaturization of structures. The use of these materials offers advantages such as reduction in weight and bulk, which is beneficial for their integration into 5G telecommunications and telephony systems. The fifth generation 5G mobile network is a set of emerging global telecommunications standards, typically using high frequency spectrum, to provide network connectivity with reduced latency and higher speed and capacity than the forerunners. It is argued that the recurring communication infrastructure is very inefficient in energy and that 5G should be designed to solve this problem, increasing energy efficiency by several orders of magnitude. To meet the demands of 5G, we need radically new network architectures and technologies, such as heterogeneous ultra-dense network, massive multi-output MIMO, and millimeter wave communications. Our goal is to achieve a planar antenna based on metamaterials which must operate at the resonance frequency of 5G which is f=3.5GHz by the CST Studio Suit electromagnetic design and simulation software and Matlab calculation.Abstract: The objective of this work is the design and simulation of an antenna based on metamaterials in order to miniaturize the dimensions of planar antennas.
