A compact hybrid CPW fed planar monopole/dielectric resonator antenna

Design of hybrid antenna consisting of a coplanar waveguide (CPW) fed printed monopole and cylindrical dielectric resonator is presented in this paper. A CPW fed printed monopole acts as an effective radiator and excites the cylindrical dielectric resonator. A wide band width of the order of 51% is achieved with the hybrid antenna. The compact hybrid antenna with moderate gain and nearly omni directional radiation characteristics is highly suitable for wireless communication with broad bandwidth or multi band to support multiple services.
