In the thesis, the first part elaborates on the design of passive components for antenna applications, including balanced to un-balanced (Balun) for balanced antenna operations. Several new wideband coupled-line baluns are proposed with improved results. The photonics bandgap (PBG) waveguide structures are applied with surface wave rejection for antenna operations. Also studied is a N-way power divider applied for array element operations. The second part of the thesis focuses on the implementation and applications of a 3D antenna system for spherical far-field measurements. The system can be applied to the measurements of antenna parameters of gain, directivity and radiation efficiency. This 3D antenna measurement system can further be applied to mean effective gain (MEG), diversity antenna measurement, and MIMO terminal antennas measurement for 3D spherical far-filed measurement. In this study, the 3D antenna system has detail experiments and setup process for practical mobile phone are investigated. The third part concludes the thesis by proposing and constructing several balanced antennas, mobile antennas and consumer electronic antennas for wireless applications.
