Abstract

The invention provides a base station antenna and base station radio frequency equipment. The base station antenna comprises a plurality of array antennas and a feed network connected with the array antennas, wherein the feed network comprises an input port for being connected with an external circuit, a power divider unit and a plurality of reconfigurable units, wherein an input end of the powerdivider unit is connected with the input port; the power divider unit is used for carrying out power distribution on a transmission signal to broaden a frequency band; the input ends of the reconfigurable units are connected with various output pends of the power divider unit separately; the reconfigurable units are used for carrying out phase reconfiguration on the transmission signal; and the output end of each reconfigurable unit is connected with one array antenna separately. According to the base station array antenna and the base station radio frequency equipment, power distribution is carried out on the transmission signal through a power divider, so that the impedance bandwidth is increased and broadening of the frequency band is achieved; and the transmission signal is subjected to phase reconfiguration through the reconfigurable units and then feeds the power.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a base station array antenna and base station radio frequency equipment with reconfigurable lobe applicable to the fifth generation communication system. Background technique [0002] With the rapid development of mobile communication systems, there is an increasing demand for base station antennas with wide lobes and wide frequency bands. In order to meet the requirements of lobes and frequency bands in practical applications, such as wider and wider coverage, in recent years, people are studying different types of linearly polarized antennas. [0003] At present, there are wide-band unidirectional multi-polarized antennas with stable wide lobes on the H-plane, but the lobe width of the H-plane is only 63.3° in the entire application frequency band. While the other can achieve a frequency bandwidth as high as 41%, while the electromagnetic dipole antenna with a wid...
