Antenna design for smart devices

The use of smart devices inreases day by day and becomes an integral part of our daily lives. Communications system started by 2G technology has evolved into 3G, 4G, now we use 4,5G in our country and in the near future will be provided by 5G communications technology. Mentioned systems need appropriate antennas which can meet required frequencies. Therefore, microstrip patch antenna has been designed and simulated with 1.8, 1.9, 2.1, 2.4, 2.6, and 3.5 resonance frequencies for being used in various technological applications.
