Automatization of EM field measurement by Narda NBM-550
Kopecký, Petr ; Bártík, Hynek (referee) ; Nováček, Zdeněk (advisor)
The diploma thesis deals with the measurement of electromagnetic fields by the meter NARDA NBM 550. The aim of the paper is to introduce the possibilities of measurement of the electromagnetic field by this device, to study the feasibility of communication with computer, to create control program and to check its functionality. A description of the electromagnetic field properties is followed by the identification of the device main functions. Additionally, the operating program is described together with the draft of measuring workplace with its realization. The results of probationary measurements are presented in the end of the thesis.

Current distribution on linear antennas
Novák, Tomáš ; Bártík, Hynek (referee) ; Nováček, Zdeněk (advisor)
This work will describe current distribution measurement problems along antenna conductor using a probe (coupling loop), which is attached to selective micro-voltmeter, which will indicate signal level (voltage). The signal level will be used for representing the current distribution. Subsequently, measuring workplace issues from generator to antenna conductor, probe and selective micro-voltmeter, will be discussed. Analysis of voltages of this link-up and additional study will be conducted. Other parameters, which complement this situation, will be calculated from the current distribution. A computer program, which calculates these parameters and speeds up the collected data processing, will be used for this process.

Measurement of the antenna directional pattern
Divín, Jan ; Bártík, Hynek (referee) ; Nováček, Zdeněk (advisor)
This Master’s Thesis is dealing with measuring antennas in far field. Especially with automation this measure, direction sensors made by optical mouse, Integrated Hall ICs for Linear and Off-Axis Rotary Motion Detection and remote unit this workplace, which can made communication with PC by USB. It describes the making control program for the PC.
