摘要
An axial mode helical dielectric resonator antenna (HDRA) for 5G applications is designed. The HDRA uses a helical dielectric resonator as source of radiation for the first time, and a conformal coaxial probe as exciter. The HDRA has advantages such as light weight, lower conductor loss, and circularly polarization. The designed HDRA has a very wide impedance bandwidth (more than 10.0 GHz), and a 3-dB axial ratio bandwidth nearly 5.4 GHz. The E- and H-fields radiation patterns are directional radiation, and the peak gain is 6.7 dBi. The front-to-back is greater than 14 dB. The simulation results show that the HDRA is a good candidate in the 5G wireless communication system.
