Abstract

This study presents the design and implementation of an enhanced Internet of Things (IoT)-based remote monitoring system for managing diesel levels and voltage status in telecommunication base stations (TBSs) to improve operational reliability and reduce fuel-related inefficiencies. A prototype system was developed by integrating ultrasonic fuel-level and voltage sensors with an Arduino Nano microcontroller and an ESP8266 Wi-Fi module. The system transmitted data to a cloud-based IoT platform for real-time visualization and automated alert generation, enabling continuous monitoring and timely notification of critical operating conditions. The system was evaluated in terms of efficiency, reliability, and cost performance under varying load conditions. The results demonstrated a 24.6% increase in monitoring efficiency, a 31% reduction in generator downtime, and an 18% reduction in operational costs compared with manual monitoring methods. These findings indicate that the proposed system offers a scalable, cost-effective, and energy-efficient solution for enhancing transparency, reducing manual oversight, and supporting more sustainable power management in telecommunication base stations. The study contributes practical evidence on the effectiveness of IoT-enabled monitoring for infrastructure management in energy-dependent telecommunications environments.

Abstract

This paper presents the design, parametric analysis, and comparative evaluation of rectangular and circular microstrip patch antennas operating at 2.45 GHz in the industrial, scientific, and medical (ISM) band for wireless communication applications. Both antenna configurations were fabricated on a low-cost FR-4 dielectric substrate (εr = 4.5, thickness = 1.6 mm) to ensure compatibility with standard printed circuit board (PCB) manufacturing processes. The rectangular patch was designed with dimensions of 38.5 mm × 29.2 mm, while the circular patch had a radius of 16.42 mm; both were optimized using cavity-model formulations and closed-form analytical equations. A 50-Ω microstrip feed line with a width of 2.88 mm was employed for impedance matching. Comprehensive parametric studies were conducted to examine the influence of geometric parameters on resonance frequency, bandwidth, and radiation characteristics. The simulation results demonstrate that both antennas achieve satisfactory impedance matching, with S₁₁ < −10 dB at the target frequency. The rectangular configuration produces a directional radiation pattern suitable for point-to-point links, whereas the circular design provides near-omnidirectional coverage with potential for circular polarization. Comparative analysis against four recent literature designs indicates that the proposed antennas achieve competitive performance in terms of compactness, fabrication simplicity, and cost-effectiveness without requiring complex modifications such as slots or parasitic elements. The study concludes that rectangular and circular microstrip patch antennas fabricated on FR-4 substrates offer practical, low-profile, and integrable solutions for WLAN, IoT, and biomedical applications requiring compact and cost-effective antenna structures.
