DEVELOPMENT OF A SHORTENED DIRECTIONAL ANTENNA OF CIRCULAR POLARIZATION Р.Л. Bychenkov Murmansk State Technical University, Murmansk, Russia yavel bychenkov1(a), mail.ru, 33806(a), mail.ru Annotation. Widely used circular polarization antennas have been analyzed. An innovative solution for the circular polarization antenna and simulation results in program MMANA-GAL have been presented. During the simulation the main parameters of the antenna device were determined. Keywords: antenna devices, circular polarization, propagation of radio waves. Introduction In the current period, the radio communication technology plays one of the most important roles in the development of any sphere, because without extensive and complex system of communication, remote control, remote monitoring and measurements technical development isn't possible nowadays. Due to the sharp increase of the number of devices using radio waves, electromagnetic environmental conditions are badly affected. It means that it is necessary to carry out further increasing of the range and quality of communication without increasing the level of radiated antenna energy. Some methods of solving this problem, such as the transition to the circular polarization of radio waves or the use of directional antennas with improved characteristics, are proposed in this project. Actuality of the project The electric component of an electromagnetic plane wave can oscillate in any direction normal to the direction of wave propagation. There are radio waves with linear and circular polarization. Circularly polarized waves get smaller losses when passing through the conductive barrier. This feature leads to the use of antennas for circular polarization (fig. 1). Физические проблемы Fig. 1. The linear and circular polarized waves Contemporary evidence can confirm the following advantages of circularly polarized waves: 1. Increased communication range in conditions of obstacles; 2. Variations of the mutual reception and transmission antenna’s position do not lead to bad influence (this is important for mobile devices); Widely used circular polarized antennas Antennas of circular polarization are used in various spheres. For example atomic icebreakers are equipped with the turnstile antenna for use in the "Gonets" satellite communications system. This system is used on ships when sailing in areas of high latitude. Another scopes of application are systems of wireless remote control (unmanned aerial vehicles) and wireless networks (Wi-Fi, WiMax), etc. 151
