A Millimeter-wave Micro-coaxial Dual-frequency High-gain Omnidirectional CoCo Antenna

This paper presents a simulation-based explanation of the mechanism of a micro-coaxial dual-frequency high-gain omnidirectional coaxial collinear (CoCo) antenna in the millimeter-wave band. Firstly, the antenna model is established, and simulation is carried out to extract the amplitude and phase of the current on the surface of the antenna radiator. Then, the dual-frequency and omnidirectional hi...
