1 TARIFF A vertical model that provides linear polarization tracking. AN ANTENNA WITH A SEPARATE SENSOR Technical Area 5 This invention is particularly useful in antennas used in Ku-band satellite communication systems, the position of the antenna reflector or the waveguide connected to the reflector It works without changing anything, simply by being integrated into the waveguide used in the antenna. around the extension axis of the orthomode transducer (OMT) It relates to an antenna that provides linear polarization tracking by being rotated. 10 Previous Technique In known satellite communication applications in technology, according to the satellite communication band... Antenna polarization changes. Antenna polarization affects the signal coming from the antenna. It describes the change in the electric field over time. If the satellite is 15 The polarization of the antenna used in communication affects the signal coming from the satellite. If the antenna of the ground satellite communication terminal is not selected according to its polarization being able to receive the signal from the satellite with a certain loss, or in some cases, not at all. It is not possible. In technical terms, the known X-band and Ka / K-band satellite communications While circular polarization is used in Ku-band satellite communication, linear polarization is used in Ku-band satellite communication. Polarization is used. In circular polarization, the electric field of the signal... Because the satellite ground communication terminal rotates in a circular fashion over time. There is no need for polarization tracking in the antenna. Linear or nonlinear. In polarization, the electric field of the signal varies along a linear axis. and therefore the antenna of the satellite ground communication terminal is the aforementioned 25 It needs to be arranged so that it is aligned with the polarization axis. Otherwise... In this case, the signal from the satellite is received with a certain loss or, in some cases, not at all. This is not possible. Therefore, especially in Ku-band satellite communication. Polarization tracking is of critical importance. In the known state of the technique, Ku-band Polarization tracking in satellite communications refers to the polarization of the signal-providing satellite or ground 30 2 by rotating the antenna used at the terminal around its roll axis or verbally This is achieved by rotating the antenna's feed around the axis of yaw. In mobile satellite communication applications, linear / transitive signals from the satellite... To receive a polarized signal without loss or with minimal loss, the antenna must be 5 the power supply or the entire antenna rolls along its axis, for example, a motor aligning the signal with respect to the polarization axis by rotating it. It is necessary. In these applications, especially antenna feeding, Serious problems arise with antenna types where the reflector is placed in front of the antenna. For example, in applications where the antenna feed is placed in front of the reflector, the antenna is 10 To rotate its feed around the axis of yaw, the feed mechanism will provide the drive for the said mechanism. A motor needs to be connected. The motor in question will supply power to the antenna. By connecting it, the motor will add a signal that reflects off the reflector and goes to the sensor. This creates a blockage, resulting in a decrease in antenna gain and affecting the antenna's performance. The lateral lobe level is increasing. 15 Another polarization tracking method included in the known state of the art is the whole the gimbal axis of the satellite ground terminal antenna, in other words, the entire antenna. It is the rotation of the antenna. In this case, the antenna, which is heavier than the antenna feed, is rotated. Because it needs to be turned, the required engine power increases, and this situation is 20 It increases the cost and engine size, thereby complicating the design. United States Regulation US2009284327A1, which is included in the known state of the art. The invention described in the patent document is for use in cylindrical waveguides. This relates to rotatable polarizer devices. The 25 described within the scope of this document... In one application, an example feed that could be a feed network for a Ku-band antenna. The network includes an orthogonal mode decoupler coupled to a cylindrical waveguide. A cylindrical waveguide contains a cylindrical tube, and the cylindrical wave cylindrical tube to facilitate connecting the guide to other components A first flange and a second flange are placed at their ends. 30 near the first flange The opening at the end of the cylindrical tube defines a common outlet port. 3 Orthogonal mode decoupler, a first coupling for connecting to a cylindrical waveguide. It includes a point. It has a structure that can rotate inside a cylindrical waveguide. Phase shifting elements are being arranged. The rotatable phase shifting element is common. It describes the cylindrical tube-shaped section extending from the mod port. It is rotatable. phase shift element, cylindrical waveguide and orthogonal mode separator along 5 It extends and is connected to a shaft that extends outwards from the vertical mode separator. The shaft and rotatable phase-shifting element form one axis of the cylindrical waveguide. It is adapted to rotate around it. However, in this document, the reflector... a phase-shifting element connected to a single waveguide placed in front of it and perpendicular The mode separator is being configured and therefore the elements in question are being driven 10 The motor, which is working to provide this, adds to the signal that will be reflected from the reflector and sent to the satellite. There is a possibility of creating a blockage. Therefore, in the current state of the technology, especially Ku-band satellite communications In antennas used in systems, the antenna reflector or 15 connected to the reflector without changing the position of the waveguide and due to the drive motor used. only the wave used in the antenna without causing any blockage It works integrated with the guide around the extension axis of the orthogonal mode separator.

These signals are... For example, these are RF signals. The polarization in question refers to the signal emitted from the transmitting antenna. It describes the change of the electric field over time, and circular polarization 20 There are two types of polarization: linear polarization and non-linear polarization. X- Circular polarization is used in Ku-band and Ka / K-band satellite communications. Linear polarization is used in band satellite communication.
