Design of Ultra Wide Band Omni Mono-Cone Antenna

摘要

This paper puts forward and designs an ultra-wideband omnidirectional mono-cone antennas used for reverberation chamber to send and receive microwave. The ground plane uses the bending design, and the cone is designed to step in order to reduce the size and weight. It is easy to take along and install. The working band of the antenna is 0.8-6GHz. Through HFSS simulation prove that the VSWR within the work frequency is less than 2. The H-plane pattern has fine out-of-roundness which less than 1dB. The E-pattern is similar to an apple and the gain is greater than 1dBi in all band. The antenna main characteristic is ultra-wideband, miniaturization and omnidirectional radiation. The antenna has good characteristics of impedance and pattern in the wide band.
