Investigation results of a new conical-shape radiation-pattern antenna based on a hybrid technique are presented. A circular-ring patch antenna excited with the dominant mode TM02 is integrated with a monopole antenna, offering two distinct operating bands. The coupling effect of the higher-order modes of the monopole and the circular-ring patch create a third operating broad band. Using this hybrid resonant configuration, the expected ripples in the E-plane pattern due to the monopole higher-order modes are alleviated over the third band, providing a good radiation performance. The measurement results performed for the proposed structure represent a good agreement with the simulated ones.
