Design and Analysis of Dual Monopole Antennas for Long-Term Evolution and Ultra-Wideband Applications: Narrow and Wide Band Variants

Abstract

Wireless communication systems continue to evolve, with LTE and UWB technologies at the forefront of this advancement. LTE (Long-Term Evolution) networks demand efficient antennas to support high-speed data transmission, while UWB (Ultra-Wideband) systems require antennas capable of operating across a broad spectrum. Monopole antennas have emerged as promising candidates for meeting these demands due to their compact size and versatility. In this study, we delve into the design and analysis of dual monopole antennas, tailored to cater to both LTE and UWB applications, with variants optimized for narrow and wide bands. The methodology adopted in this study involves a systematic approach to antenna design and analysis. Initially, the design parameters are carefully chosen to meet the frequency requirements of LTE and UWB systems, considering both narrow and wide band variants. Advanced simulation tools are employed to optimize the antenna geometry and ensure impedance matching across the desired frequency bands. Additionally, rigorous electromagnetic analysis techniques are utilized to evaluate radiation characteristics, including antenna gain, directivity, and radiation efficiency. Through iterative refinement and optimization, the performance of the dual monopole antennas is systematically enhanced to meet the stringent requirements of LTE and UWB applications. The results of our study demonstrate the efficacy of the proposed dual monopole antennas for LTE and UWB applications. The good agreement is observed in the measured and simulated return loss with a narrow bandwidth of 0.45 GHz (1.65 to 2.10 GHz) for LTE band and a wide bandwidth of 12.42 GHz (4.74 to 17.16 GHz) for UWB applications.
