Takta Company’s Antenna Testing Center is the only far-field antenna parameter testing center in the Middle East for testing and experimenting with various types of telecommunication, television, and FM antennas in an area of ۳۳,۰۰۰ square meters on the edge of the Karaj-Qazvin highway, which was established in 1976 in cooperation with Scientific Atlanta (S.A.) and the National Iranian Radio and Television Organization at that time.
The devices and equipment of this center are capable of testing various necessary parameters such as gain, radiation pattern, directivity, polarization, axial ratio, and impedance parameters (Z, Return loss, V.S.W.R) of any type of antenna at different frequencies and by far-field method.
The transmitter section includes a synthesizer-type signal generator that produces the desired frequency signal with high frequency stability; in this way, the signal produced by the transmitter antenna is radiated. In the receiver section, the antenna under test is rotated around its axis by the positioner at an appropriate speed, and during rotation, the received signal is transmitted to the LNA system and spectrum analyzer at any moment by the Low Loss cable.
The maximum received signal power is measured at any moment by the spectrum analyzer and the received signal power information is transferred to the computer via the GPIB cable and at the end the available information is plotted as a radiation pattern by the software program prepared by Khajeh Nasir University in the Matlab environment.
The antenna center is currently operating as the only standard center for testing and measuring antennas in various parameters in the country. After equipping this center, considering the capacities of the Tekta Company’s antenna center in Alborz province, it will be used almost daily by all domestic antenna manufacturers, designers and researchers, including the Iranian Broadcasting Organization, the Iranian Telecommunications Company and affiliated companies and various telecommunications industries, military forces, universities, etc.; so that this center, before belonging to a specific company or organization, is operating as a national center serving the country’s industry to meet the needs in this area.
This center is equipped with the necessary and unique equipment in the country and is capable of measuring telecommunication antennas from small diameters to 3 meters in diameter with a measurement frequency range from 100 MHz to 18 GHz.
In recent years, the analogue systems of the antenna center, which had been installed and commissioned for a long time and had lost the necessary accuracy, have been updated to meet the current needs of the country and have been equipped with spectrum analyser and synthesizer measuring devices, LNA and GPIB board and Low Lass cables to increase the measurable frequency range to 20 GHz.
Takta Antenna Center covers more than 4,000 square meters of covered space and is equipped with special radio equipment suitable for testing and evaluations, as well as using well-equipped machinery and mechanical workshops in a special welding workshop (argon and aluminium) and a plating workshop to meet the domestic need for tests.
Takta, relying on the capabilities of experienced and renowned specialists in the center’s fields of activity and its relationship with foreign professors in this field, has been able to achieve many impressive successes over the past 5 decades.
