Study and conception of an antenna in the UHF band

Abstract

Microstrip antennas are essential for various applications for data analysis and communications. This study aims to design and study antenna structures adapted to UHF communications systems. We also worked on a traditional antenna using a CST simulator to obtain accurate results, which resulted in a narrow band with wide dimensions. We moved to two antennas in the same plane, which led to an increase in bandwidth, and a decrease in gain and directionality. A miniature antenna was added to the element and reduced Its size, resulting in a wide bandwidth with high gain and efficiency.
