Magnetic loop antenna with electronic tuning for frequencies below 30MHz
Burda, Miroslav ; Láčík, Jaroslav (referee) ; Urbanec, Tomáš (advisor)
This project deals with electronic tuning and automated adjustment of magnetic loop antennas, working in the High Frequencys. The whole work is divided into three parts tuning, adjustment and control). The tuning part is realized by changing the capacity of the array capacitors and adjustment is done by different changes of power points. The whole system is controlled by a microprocessor ATmega16. According to utility switches the microprocessor capacity, which tunes the antenna to the required frequency, processes information about power adjustment and fine-tuning the antenna by changing the position of charging.

Magnetic Loop Antenna with Electronic Tuning for Frequencies below 30MHz
Svoboda, Luděk ; Vágner, Petr (referee) ; Urbanec, Tomáš (advisor)
The aim of this bachelor's project was realization of a tuning system with complete software and testing of the system's functionality and parameters of antenna. The system is divided into two parts, tuner and controller. The tuner implements change of circuit capacity by switching capacitor series. For switching is used transistor with small transitional capacity but small maximal collector current, too. This parameter restricts the use of system. The second part, controller, uses microcontroller AT89C2051. The microcontroller switches capacitors (and thus sets frequency) according to requests sent from PC with control software. The functionality was checked by tests with network analyzer.
