A New Compact Dual-Polarized Integrated Antenna Array for 2G/3G/4G/LTE Base Station Applications

摘要

A new compact dual-polarized integrated antenna base station (BS) array is proposed in this paper. It consists of one center linear arrays and two side one with their total size of only 356×1000×81mm³. The center array is operated in full-band (0.69-0.96 /1.7-2.7GHz) while the two sides arrays worked in high band (1.7-2.7GHz). The full-band elements are designed based on both our new high band feeding and low band (0.69-0.96GHz) Electromagnetic (EM) dipole techniques. The main performance features of the BS array, i.e., cross polarization discrimination (XPD) and 15 (11) dBi gains in their high (low) frequency band respectively, are fully designed and obtained by using simulations. The validities of the design are verified by the measurements, showing that the BS array have good potential applications in wireless BS.
