Abstract :
We show how a high dispersion composite right/left-handed (CRLH) metamaterial leaky wave antenna can be operated both for scanning surveillance and for null tracking. The antenna presented, unlike previous leaky wave scanning antennas, requires only a narrowband frequency excitation range, 450MHz for -680 to +270 scanning including broadside for 2GHz center frequency operation. A design methodology for antenna synthesis is presented and experimental results based on a 2GHz antenna are presented. The resulting antenna should find application in RFID localization equipment.
