Abstract

This paper presents the design, simulation, and optimization of an advanced miniaturized L-shaped microstrip patch antenna operating at 17 GHz for 5G applications. The proposed antenna employs a Rogers RT/Duroid 5880 substrate to achieve minimal dielectric loss and enhanced gain. Through meticulous design and parameter optimization in HFSS, the antenna achieves excellent return loss of -37 dB, ensuring minimal signal reflection and enhanced impedance matching. The compact L-shaped structure enhances bandwidth of 4.5dB and radiation efficiency of 99%, making it suitable for dense urban environments, small cell deployments, and point-to-point communication. The simulation result demonstrates a stable radiation pattern, low voltage standing wave ratio (VSWR), and improved gain, positioning this design as an efficient solution for next-generation 5G communication systems. Future work will explore on Bandwidth and Return Loss for 5G applications. The swift advancement of wireless communication technologies has created a demand for high-performance antennas that can operate in the milli meter-wave (mm Wave) frequency range. The deployment of 5G technology has significantly increased demand for compact, efficient, and high-gain antennas that can support high data rates, low latency, and seamless connectivity. Among the various frequency bands designated for 5G applications, the 17 GHz band has gained attention due to its potential for high-speed communication, reduced interference, and suitability for various wireless applications, including satellite communication, autonomous vehicles, and radar systems.
