Design and Simulation of Low Power 5g Antennas for Mobile Devices

Abstract

The deployment of 5G technology marks a revolutionary leap in wireless communication, offering ultra-fast data rates, low latency, and massive device connectivity. As mobile devices demand smaller hardware footprints and longer battery life, the necessity for efficient low-power antenna designs becomes critical. This paper explores the design, simulation, and analysis of low-power 5G antennas with a primary focus on microstrip patch antenna configurations. It investigates their performance in terms of return loss, gain, directivity, and power consumption. Simulation studies were conducted using HFSS and CST Microwave Studio to evaluate the performance of various antenna geometries operating at mmWave frequencies (specifically 28 GHz and 38 GHz). The results demonstrate that optimized microstrip patch designs can meet the dual goals of efficiency and miniaturization without compromising radiation characteristics. This study contributes to advancing compact antenna technologies for the future of mobile communications.
