چکیده
Very high wind loads represent one of the major problems for ultralarge-scale 5G base station arrays in sub-6 GHz band, where dozens or even hundreds antennas are used. An ultracompact dual-polarized cross-dipole antenna with an extremely small overall projected area is presented. The reduced by employing miniaturized cross dipoles and replacing traditional ground plane a defected structure (DGS) metal mesh reflector. DGS utilized size reduction isolation enhancement. Therefore, array low load formed using area, each can be independently packaged streamlined radome that conducive to airflow. prototype designed, fabricated, measured sub-1 band. results show impedance bandwidth 680–970 MHz, polarization higher than 20 dB, gain approximately 6.5 dBi. Furthermore, verify proposed excellent radiation performance highly suitable load.

Wideband Dual-Polarized Crossed-Dipole Antenna with Parasitical Crossed-Strip for Base Station Applications
A wideband dual-polarized crossed-dipole antenna with parasitical crossed-strip for basestation applications is presented. By using a pair of orthogonal crossed-dipoles, two linear polarizations (±45◦) are obtained. A parasitical crossed-strip is introduced to improve the impendence bandwidth and enhance the isolation (S12) between the two orthogonal polarizations of the upper band. The antenna...
متن کاملA Compact Dual-Band Dual-Polarized Antenna for Base Station Application
A compact dual-band dual-polarized antenna is proposed in this paper. The two pair dipoles with strong end coupling are used for the lower frequency band, and cross-placed patch dipoles are used for the upper frequency band. The ends of the dipoles for lower frequency band are bent to increase the coupling between adjacent dipoles, which can benefit the compactness and bandwidth of the antenna....
