A wideband hybrid feeding circularly polarized magneto-electric dipole antenna for 5G Wi-Fi

摘要

A hybrid-fed circularly polarized magneto-electric (ME) dipole antenna is presented for 5G Wi-Fi application. A single series feeding cross-aperture coupled structure is used to stimulate the ME dipole antenna. Measurement shows that the ME dipole antenna has an overlapped bandwidth of 23.5% from 4.98 to 6.31 GHz for the standards of both |S-11|-10 dB and axial ratio3 dB. A measured gain of approximately 7.5 dBi is obtained and the fluctuation of the realized gain is 1 dB from the whole operating frequency band. Moreover, because of the advantages of ME dipole, the proposed design realized a stable radiation patterns and roughly coincide radiation patterns at x-o-z and y-o-z plane in the operating frequency band.
