In this study, a new spiral dual-band antenna integrated with an optical system for a small
CubeSat spacecraft was proposed. It is challenging to design an antenna with a limited …

Star sensors are commonly used in satellite navigation systems to determine the orientation
of spacecraft, which is crucial for accurate navigation and control. One of the key factors …

Entropy as a mathematical concept is the first of its own kind, and second to none. Barely
one or two papers in literature have investigated fractal dimensions of very basic entropies …

This article discusses the possibilities of using fractal antenna systems in wireless
communication systems, their features and the main advantages of using them. The …

This document presents the design, simulation, and characterization of a UWB antenna,
starting from a rectangular patch antenna. The initial modifications included adjustments to …

A novel low profile Split and Rotated Microstrip Patch Antenna (SRMPA) with improved
antenna performance is presented. The proposed antenna overcomes the limitations of the …

As a mathematical concept, entropy is the first and most advanced of its kind. Only a handful
of studies have examined the fractal dimensions of fundamental entropies, including …

One of the future challenges of increasing the harnessed solar power is efficiency using of
CubeSat sides. One of the approaches is using integrated antenna systems with solar …
