The designed asymmetrical slots offer greater flexibility in antenna design and easier control of crucial antenna parameters such as gain, side lobe suppression and bandwidth. Besides we designed it to be useful for frequency range 24.25-27.5 GHz and therefore it is suitable for future great capacity broadband 5G technologies.
