Here we focus to design a microstrip patch antenna on a 5G/6G application. Here we aim to design an antenna that works on GHz. In this project, we used a rectangular patch with a dielectric constant of 2.0 and dielectric loss of 0.0010 here an antenna with Ghz frequency will be designed with CST Tool. In this project we use the microstrip feed method while designing the antenna we should keep in mind MIMO and beam steering. The demand for high-speed data communication and the Internet of Things (IoT) has led to the development of fifth-generation (5G) and sixth-generation (6G) wireless communication systems. Antenna design plays a critical role in these systems as they require high gain, low side lobe levels, and beamforming capabilities to support millimetre-wave frequencies. Computer Simulation Technology (CST) is a powerful tool for designing and simulating antennas for 5G and 6G systems. This paper discusses the use of CST in antenna design for 5G and 6G systems, including the design specifications, 3D modelling environment, solver algorithms, and simulation tools. The paper highlights the importance of phased array antennas in 5G and 6G systems and the role of CST's simulation tools in designing and optimizing these antennas. Furthermore, the paper discusses the impact of the environment on antenna performance and how CST's simulation tools can be used to model these effects. In conclusion, CST provides an excellent platform for designing and simulating antennas for 5G and 6G systems, enabling designers to create efficient and effective antennas that meet the specifications of these systems.
