Abstract

A new four-element cylindrical dielectric resonator (CDR) array is proposed as a wideband low profile monopole-like antenna. Unlike previous investigations, the present antenna is easy to design and excite as it employs the dominant HEM_11delta mode in each CDR. Ansoft´s HFSS based design data and experimental results are presented. As much as 29% matching bandwidth (S₁₁<-10 dB) with monopole-like radiation pattern over the entire band has been achieved with 4 dBi peak gain from a prototype occupying a very compact space measuring 0.6lambda₀ by 0.1 lambda₀ approximately
