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.
