Abstract
The next generation of mobile communication system is the fifth generation (5G) communication systems that used mm-wave bands to achieve high data rates and increase the user capacity. 5G communication system require a low profile, lightweight, high gain and simple structure antennas to ensure reliability, mobility, and high efficiency. Due to the low atmospheric absorption rate of electromagnetic waves at 28GHz, this paper aims to design a directional single element slotted microstrip antenna with compact size to operate at 28GHz for 5G applications. The proposed antenna is simulated by using High Frequency Structure Simulator (HFSS) software on FR4 substrate with 4.4 dielectric constant, 0.8 mm thickness, and 0.02 loss tangent. In order to achieve the requirements of the proposed antenna, the patch is modified by loading specific slots; and the performance of the antenna is studied in terms of antenna parameters that are return loss, VSWR, gain, and radiation pattern, and compared with published results.
