Optimering av antenndesign utifrån experimentella data / Optimization of antennadesign on the basis of experirments data

<p>During the work at Gateway Security AB in Motala I began examining available antenna models to get a wider perspective, this have given knowledge of their structure, and an understanding of their function. All my necessary fact is based on my observations and notes of these measurings. </p><p>New antenna models, and available models were examined where measurements at different heights and different distances on the antenna were performed with the help of an oscilloscope and a measure probe, peak – to - peak was brought on the signal. The measurements are presented in a line diagram. </p><p>Further development of simulating tool for antenna designs have been made. Calculations of electromagnetic fields from the antenna take place in the simulation programme Wire-MoM, where the antenna is fed in as a thread structure. I used the data from this programme to present the appearance graphical in 2-dimension in Matlab. Further development represents an improvement of the result presentation management of the simulating tool. </p><p>The results are presented graphical and show the fields at a height of for example 1 meter. Conclusions where taken on the basis of comparison of my results from all the measurements and the graphical image.</p>
