Antennae are very fundamental in the world of telecommunications.They play avital role in the effective transmission of signal to the end-users.In order to maximize theefficiency (in terms of coverage) of an antenna array, companies have to develop and testdesigns before producing them.The rapid growth of processed data this day and age hascreated a platform for the expansion of knowledge.However, gathering consequentialinformation is difficult when the data is in large quantities and in different formats.However, without the use of a visualization software, this process of maximizing theefficiency is tedious and costly.As a result, many companies turn to software developersto obtain a custom software solution that is user-friendly and packed with all the featuresthat they would require (e.g.generating multiple circular and/or linear graphs).　　The purpose of the thesis is to design and implement an antenna radiation patterndata management visualization software (which will be abbreviated as ARPDMV) whichmanages data by sorting it and calculating the antenna parameters.The system will showthe radiation patterns and frequencies in antenna array.Creation of the software-will becarried out using a C++ framework called QT creator.It is a good choice because itmakes it easier to manage data due to its tree model characteristics.The ARPDMVshould be able to read data (near-field and far-field measurements) from multiple filetypes, display antenna properties, calculate antenna parameters and generate the variouscartesian and polar plots of the radiation patterns as required by the user.This would be agreat advantage in that the user will be able to analyze the radiation patterns effectivelyhence being able to have knowledge concerning the antenna performance.Moreover, itwould provide a simple but effective user interface (UI) thus allowing the user to takefull advantage of all the features of the program.As a computer program, it will consistof three layers: the UI layer, the computational layer and the data layer.
