Abstract

Antenna arrays have been used for many years due to their many applications. However, these arrays can be further improved in many ways. In this thesis, directive antenna arrays such as Yagi antennas and LPDA antennas are analyzed. First, a conventional Yagi is improved by reducing the element-length and by making the antenna circularly polarized. The antenna is optimized to achieve the best results. Next, an electrically small broadband cross dipole is investigated. An analysis of where the antenna fits along the () curve is conducted. Next, a previously reported 15-element, size-reduced, Yagi is improved through the implementation of dual-band elements and is compared with a conventional full-sized 15-element Yagi. Finally, further analysis on a wideband, circularly polarized, log periodic dipole array, is performed.
