Antenna efficiency Measurement in reverberation chamber in microwave band

Ehsan Poodineh, Defended in January 2020

In this project, the performance of RTS60 reverberation chamber located at KN Toosi University’s WiTeM laboratory is studied and simulated. The field uniformity parameter of the chamber is simulated for three different stirrer locations is simulated and shown that for all stirrer locations this parameter is below the 3 dB threshold value defined by the standard. Next, the field uniformity parameter is practically measured by the electric field probe and compared with the simulation results and is shown that both of the simulated and measured results are below 3 dB. In the second part of the thesis, different methods of measuring the antenna efficiency in the reverberation chamber are investigated and by full wave simulation of the reverberation chamber. The total efficiency of a horn antenna for 25 different locations of the stirrers is simulated by using two methods, which are reference antenna method and single antenna method. In both cases, the full wave simulation of efficiency measurement have an error of better than 20%.

Elimination of Radiation Pattern Null in Microwave Orbital Angular Momentum (OAM) Systems

Elaheh Shamoushaki, Defended in September 2019

The capacity and the security of a communication link are two essential properties of communication systems. Orbital angular momentum (OAM) is a property of electromagnetic waves with helical phase front which can be generated in different methods such as circular array antenna, horn antenna with spiral phase plate, etc. Orthogonality of different states of OAM makes it possible to simultaneously transmit an infinite number of data on independent channels at a single frequency and increase the channel capacity. The transmitted information can be encoded in different states of OAM, which makes the communication link secure.

Simulation and optimization of EMC measurement chambers based on CISPR standard

Amir Sahraei, Defended in January 2019

The electronic devices in modern world play an important role in human life. Several electronic and electromagnetic devices are had to work very close to each other and most devices are integrated now days. Every electronic device is able to radiate electromagnetic waves which could affect other devices performance. The simplest effect of electromagnetic waves interface is damaging the electrical board and disabling the electrical circuit, however, this damage could be more dangerous and even cost financial losses or even casualties. several international standard organizations are formed to produce appropriate standards and limitations to reduce the risk of electromagnetic interface. These standards are entitle ‘EMC ’ standards. The EMC standards have been expanding and it is necessary to update regularly. For testing devices base on EMC standards, it is need to construct standard anechoic chambers. Therefore, here, necessity of EMC will be discussed. Due to the fact that electromagnetic absorbers are important part of EMC anechoic chambers, they will be studied. Then other consideration of anechoic chamber will be discussed. The international EMC standards will be studied and base on these standards an GTEM Cell will be designed and fabricated which is one of the EMC chambers.

Design, Simulation, Miniaturization and Optimization of Ground and Air antennas of a UHF Meteorological Radiosonde System

Farahad Ghorbani

Radiosonde system is one of the modern systems that measure meteorological variables. This system consists of two parts, the ground station and Radiosonde transmitter system. Radiosonde carried by airborne balloon and is equipped with various sensors to measure temperature, humidity, air pressure, direction and wind speed. After measuring the parameters, the measured data Send by radio transmitter to the ground station. Radiosonde transmitted measured data at 403MHz and 1680MHz radio frequencies. At high altitudes, airborne balloon’s orientation is affected by the winds of the atmosphere above the ground and it is impossible to determine precisely the direction of its movement. That's why we need an omnidirectional receiver antenna at radiosonde working frequency in order to receive information from transmitter. From various design options, the 6-segment patch antenna is an appropriate choice. According to the features described, the antenna in the picture is designed as 7 separate patch antennas at 403MHz frequency. Easy to carry, Lower weight than similar models, no need for Radome coatings, affordable prices and easy installation are the Features of this design. also The design of this antenna is such that only with changing the upper part of the antennas makes it possible to change the working frequency from 403MHz to 1680MHz

Reza Asadi

n this thesis, we briefly review the effects of RF waves’ exposure on human health and compare the common standards in this area. Afterwards, using the above results, the current level of waves in the Faculty of Electrical Engineering in K. N. Toosi University of Technology, in the range of 860 to 950 MHz and 2.4 to 2.5 GHz, are measured. The resulted RF map, comparing the level of the signals with the existing standards, has been produced.
