A two‐dimensional beam steering array composed of an eight‐element antenna array using composite right/left‐handed leaky‐wave antennas fed by an 8 × 8 Butler matrix network is designed at X‐band. An eight‐way beam switching in one direction by input port switching and a continuous beam steering in the other direction by frequency sweep are achieved. A wide range beam steering operation covering from −55 to +53 degrees by port switching and from −37 to +27 degrees by frequency sweep is demonstrated with the maximum gain of 9.2 dBi.
