TY - JOUR ID - TI - Design and Simulation of Rectangular Microstrip Patch Antenna Using a Computer Simulation Technology Operating at 4.5 GHz AU - Saad N. Ali, Faris S. Atallah, Abdullah H. Muhammad PY - 2023 VL - 19 IS - 2 SP - 53 EP - 55 JO - Iraqi Journal of Applied Physics المجلة العراقية للفيزياء التطبيقية SN - 18132065 23091673 AB - The demand for mobile phones with contemporary services like Bluetooth, wireless local area network (WLAN), and interoperability has recently increased. This has led to significant growth in mobile wireless communication system networks for WiMAX microwave access exist everywhere. A model of microstrip antennas for WiMAX/WLAN applications is included in this study. The suggested model was created and analyzed using the 2019 Computer Simulation Tool (CST), which has created and sold high performance 3D electromagnetic simulation tools to simulate electromagnetic fields across all frequency bands. A set of mathematical relationships used to design the micro-band antenna was used to get the design with overall dimensions of 49x41.9 mm3 to enhance antenna performance and the radiator plate has a rectangular shape. It has a bandwidth suitable for network services, operates at resonant frequencies, has overall dimensions of 23x17.5 mm3, and has a very low radiation loss of -20.2 dB, making it suitable for WiMAX/WLAN network services. The values of gain, return loss, percentage of stopping voltage, bandwidth, and current distribution were acceptable.
