    Dual band U-slotted Microstrip Patch Antenna for 5G Mobile Systems
    (Department of Electronic and Telecommunication Engineering, 2022-11) Mahabub, Fahim Bin
    This research focuses on 5G mobile applications for high-band millimeter waves. The goal of the suggested microstrip patch antenna was to function at 28 and 38GHz, the first and most popular 5G frequency bands. In this work, a single rectangular patch, which is frequently used in other 5G antennas, is combined with a variety of two U slot shapes in order to improve the gain and other radiation properties of the antenna. Using CST Microwave Studio's electromagnetic simulation software, the suggested antenna has been built and investigated on a Rogers RT Duroid-5880 substrate with relative permittivity of 2.2. The designed antenna's gain, bandwidth, return loss, VSWR, and efficiency are 9.12 dBi, 700 MHz, -23.79 dB, 1.1, and 75% for 28 GHz, and 9.77 dBi, 950 MHz, -41.76 dB, 1.01, and 84% for 38 GHz respectively. The proposed antenna has a good chance of being used for 5G mmWave cellular communication
