Abstract
The invention discloses a broadband dual-band base station antenna array with high out-of-band isolation, having at least one high-frequency antenna unit, one low-frequency antenna unit and a floor; when there is one high-frequency antenna unit, it is placed on one side of the floor; when there are more than one high-frequency antenna units, they are placed on both sides of the floor. The high-frequency antenna unit includes multiple dipole arms and a balun, wherein the dipole arms are connected by distributed inductor and fed through the balun; the low-frequency antenna unit including multiple dipole arms and a balun is placed on the middle of the floor, wherein the dipole arms are connected by distributed capacitor and fed through the balun. The balun is provided with a feeder and a H-shape microstrip line. The H-shape microstrip line connects with the feeder.
