A new steerable-dielectric resonator antenna is described. It consists of a movable annulus of heterogeneous dielectric sections surrounding a cylindrical core of another dielectric. The antenna far-field radiation was found to be manipulated by changing the angular position of this ring. This antenna demonstrates resonance at ~1.2GHz with a fractional bandwidth of 28.3 (S11<-10dB), confirming an HFSS simulation of the same structure. © The Institution of Engineering and Technology 2007.
