In this talk, we will propose a filter-integrated method to improve the stability of the radiation patterns of the compact planar UWB antenna, especially increasing the broadside realized gain values at the higher portion of the UWB frequency range. As is known, with the rapid development of UWB technology for commercial communication applications, many practical applications, such as portable devices,...
A novel electrically small uniplanar antenna with pattern-agile performance is reported. It consists of a split semi-loop connected to the ground strips of a coplanar waveguide-fed semi-loop antenna. The angle of its maximum directivity can be controlled simply by changing the position of the gap in the ground-connected semi-loop. The measured results of this behaviour are in good agreement with the...
