Abstract

The invention discloses a feed network of a splitting antenna and the splitting antenna. The feed network comprises a cavity, a printed circuit board (PCB) and at least two radio-frequency signal input ports, wherein the cavity comprises an upper ground metal plate and a lower ground metal plate; the PCB is arranged in the cavity; a splitting network circuit in the feed network and a phase-shifting circuit are integrated into the PCB; a wire on the PCB is in a strip line structure as a whole through the arrangement of the PCB and the cavity; the at least two radio-frequency signal input ports are connected with the splitting network circuit in the PCB; after radio-frequency signals input by the at least two radio-frequency signal input ports sequentially pass through the splitting network circuit in the PCB and the phase-shifting circuit; at least two wave beams with an included angle there-between are formed through an antenna element of the splitting antenna; and integration of the splitting network circuit and the phase-shifting circuit is achieved, so that the feed network structure of the splitting antenna is simplified; and the reliability of passive intermodulation PIM of an antenna system is improved.

Description

technical field [0001] The embodiment of the present invention relates to the communication field, and in particular to a feed network of a split antenna and a split antenna. Background technique [0002] With the development of Mobile Broadband (MBB) and the increase in the number of users, network capacity has increasingly become a bottleneck for the development of Universal Mobile Telecommunications System (UMTS). , Add multi-sector networking, or use split antennas. The split antenna increases the vertical dimension partition of the service information channel by increasing the number of main equipment channels, improves the spectrum efficiency, and then increases the network capacity. [0003] When the split antenna is applied to the Long Term Evolution (LTE) technology, the radio frequency system of the base station has higher and higher requirements on the technology of the base station antenna, which is mainly reflected in Passive Inter-Modulation (PIM). PIM refers...
