A 3D Printed Dual Circularly Polarized Antenna for Millimeter-Wave Applications
2019 International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM)（2019）
摘要
A dual circularly polarized antenna array using 3D printed technique is proposed for millimeter wave (mm-wave) applications. In this design, the two polarizations share the common radiating element and 90° orthogonal wave-guide feeding network. As a result, their performance in the aspect of impedance bandwidth, axial ratio (AR) bandwidth, and gain is nearly identical to each other, which could meet the demand of future 5G mm-wave applications.
