Abstract
A two-dimensional periodic mushroom structure is proposed as a leaky-wave antenna with a conical beam. To the author´s knowledge, this is the first 2D leaky wave antenna demonstrated experimentally. The structure can be modelled as a composite right/left-handed (CRLH) transmission line and exhibits both backward and forward leakage. The radiation patterns for the antenna are shown and demonstrated a scanning range of 15°-33° in the backward region and 27°-63° in the forward region.
