Résumé :

Digitalization is becoming more and more important. Building smart houses and industries to offer humans longer lives is one of the main goals of the digitization movement. The main aim of this work is to make those verbal exchange modules more powerful with the aid of either improving the antennas to have a higher layout or changing it with new varieties of antennas that are better able to facilitate powerful verbal exchange. This paper proposes an antenna that can be applied to a verbal exchange module to be able to perform inside the Industrial, Scientific, and Medical (ISM) band at 2.4 GHz

Résumé :

Research in the field of planar inverted antennas with multiband frequencies is currently being developed. Due to the hugely increased number of mobile users, at least every time a new generation is released, a mobile communication system is released with additional features. All additional features of a mobile communication system require an antenna that resonates over a specific frequency spectrum range, meaning multiple antennas are required in a single mobile device to function across all generations for all frequency spectrums. To reduce the number of antennas on a mobile communication sy

Résumé :

Because the direction of a single antenna is limited, and for strengthening the direct radiant ability of the antenna, we will put the weaker direction antennas together in some way to constitute an antenna array system. The antenna array is also called the array antenna or a disperse antenna array. The antenna cell can be the symmetry center-fed dipole, the aperture antenna, the circle antenna or other forms of the antennas whose direction are limited. In practice, the antenna array is almost constituted of similar antenna cells. I have mainly completed the antenna array direction diagram in

Résumé :

RF front-end system in the mobile communication system consists of an antenna, filter, and amplifier section. Now a day, there is a need to reduce the size of this RF front-end system. Here the challenge is the reduction in the size of the RF front end without degrading the performance. One way to reduce the size is by reducing the size or area of the antenna. This work proposes and simulates three Bio-inspired microstrip (BIMS) antenna designs. They are flower, Butterfly, and leaf shapes presented based on the perturbation method, Gielis super formula, and modified polar transformation models

Today, the effectiveness of the troop and weapons management system has become as much a factor in winning a battle as their quantity and quality. In modern conditions, the management of troops and weapons is almost entirely based on the use of various radio-electronic means, which in turn made it possible to increase the effectiveness of fire damage to the forces and means of the opposing side and significantly improve the quality of the management of troops.  Since radio emission detection and analysis systems receive information from existing electromagnetic fields, receiving antennas
