摘要：

The concept of an antenna based on a loaded annular dielectric resonator (DR) is further developed. In this work it is shown that loading of an annular DR inner wall with a one-dimensional array of metalized periodic elements can induce versatile responses. Such loads appear to behave like the electromagnetic band-gap structure (EBG) affecting primarily the field line terminations around the loaded area. It is shown here that such antenna can produce a narrow or wide stop-band or just a wideband response using the same resonator. In all the cases the antenna demonstrates HE11 delta mode resonances outside the bandwidth of a simple cylindrical annular DR of similar dimensions and the same epsilon(r) value.
