Conical beam antennas are widely applied in many civilian and military systems. Research on conical beam antennas is one of the key points to promote the development of the RF systems in communication, detection and guidance applications. There are still many challenging problems in the realization and pattern synthesis of the conical beam antennas with circular polarization, wide bandwidth, large beam-pointing angle and reconfigurable capability. This paper presents the overview on the research progress of the conical beam antennas including that in our group, sketches the fundamental theory and the key technology of the conical beam antennas. Finally, the key issues in the future development of the conical beam antennas are discussed.
