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 simulated values. A peak realised gain of 1.93 dBi is achieved experimentally. The radiation efficiency is observed to be higher than 95% for every angle selected.
