Abstract

The rapid expansion of wireless communication systems, particularly in WiFi networks, underscores the need for efficient and high-performing antennas. This paper addresses this requirement by presenting the design and simulation of a dual-band rectangular microstrip antenna tailored for wireless local area network (WLAN) applications. The proposed antenna features a rectangular patch with two pairs of slots positioned on opposite edges, fed by a microstrip line. These slots are strategically designed to produce two distinct resonant frequencies at 5 GHz and 6 GHz The design methodology incorporates standard equations for rectangular patch and microstrip antennas to determine the optimal patch size, feedline position, and slot dimensions. Following this, a 3D modeling software is utilized for simulation. This tool enables detailed electromagnetic analysis and provides a range of param eters and plots, including return loss, voltage standing wave ratio (VSWR), input impedance, current distribution, radiation pattern, and gain, facilitating a thorough evaluation of the antenna’s performance. The anticipated results suggest that the antenna will achieve a VSWR of less than 2, with peak gains of 2 dBi at both 5 GHz and 6 GHz. The proposed antenna is expected to be well-suited for dual-band WLAN applications, offering advantages such as a compact size, simple structure, and low cost, thereby meeting the growing demands of modern wireless communication systems

Abstract

Cube satellites are typically used as platforms for experiments and observation. Therefore, a reliable electrical distribution system is needed to ensure the cube satellite can operate stably and optimally. In this research, a prototype system was designed and implemented based on needs analysis and specifications. The developed system has functions such as the ability to control power harvesting conditions, electrical distribution, as well as monitoring the voltage on solar panels and batteries. Thanks to the testing conducted, it was proven that this system works correctly and can be an effective solution to improve the performance of cube satellites in future research. Keywords: electrical power system, satellite electrical distribution
