A Dual-Band Dual-Polarized Antenna For 5G Micro Basestation Applications
2021
This paper presents a cross dipole antenna for the fifth generation (5G) sub-6 GHz dual-band applications. The proposed antenna mainly consists of eight copper radiating patches, eight parasitic patches, and a reflector. The proposed antenna can achieve a ±45° polarization characteristic. The overlapped bandwidth is 2.77-5.31GHz, and the corresponding gain varies from 7.6 to 8.4 dBi. The gain increases with increasing operating frequency. Besides, the cross polarization level is less than -28 dB while the port isolation is larger than 26 dB.
