Abstract

The embodiment of the invention provides a feed network and an antenna to reduce passive intermodulation interference and to improve the reliability and the stability of the antenna and the mobile communication quality. The feed network comprises at least two independent radio-frequency transmission areas. At least two signal lines are erected in at least one of the two radio-frequency transmission areas. At least two independent radio-frequency transmission areas are isolated by using a metal isolating layer. One physical surface of the metal isolating layer is exposed out of at least one of the two independent radio-frequency transmission areas. The other physical layer of the metal isolating layer is exposed out of the other independent radio-frequency transmission area. Since the radio-frequency transmission areas of the feed network provided by the invention are isolated by using the metal isolating layer and are not connected by using screws or rivets, the passive intermodulation interference caused by metal connection is reduced, the reliability and the stability of the antenna are improved, the received total wideband power (RTWP) or the received signal strength indication (RSSI) of a system is improved and the mobile communication quality is improved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a feeding network and an antenna. Background technique [0002] In a wireless communication system, as voice and data information need to pass within a fixed bandwidth increases day by day, passive intermodulation (Passive InterModulation, PIM) becomes an important factor restricting system capacity. PIM is a frequency interference caused by the nonlinear characteristics of various passive devices in the transmission system. For example, in high-power, multi-channel systems, the nonlinearity of passive devices will generate higher harmonics relative to the operating frequency , these harmonics mix with the operating frequency to create a new set of frequencies, just as two or more frequencies mixed together in an active device create spurious signals in a nonlinear device. When the spurious intermodulation signal falls within the receiving frequency band of the base station...
