- Abstract
A four - element vortex electromagnetic antenna array and feeding network were designed in millimeter wave band. The antennas array composed of linear polarization microstrip antennas are fed with feeding network containing microstrip power splitter and microstrip phase shifter. The structure which is simple and easy to implement requires only one feed port to produce a mode 1 vortex electromagnetic wave. And the phase error is small because the feeding network is symmetrical in the center. The microstrip antenna is fed with the coaxial cable through the ground plane in order to reduce the impact of the feeder network on the radiating element. The simulation results show that a vortex electromagnetic wave with a center frequency of 33. 22 GHz and a bandwidth of 1. 86 GHz is generated and its maximum gain is 8. 6dB.
