Problems solved by technology

[0003] Due to the limitation of the size of the radome and the reflector of the base station antenna, it is often difficult to achieve a safe isolation distance between the radiating elements. Superposition with the incident wave leads to serious deformation of the pattern
[0004] In addition, electromagnetic waves scatter and resonate through metal boundaries such as reflectors and partitions. On the one hand, it leads to beam skew, deformation, and grating lobes. On the other

Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] combine Figure 1 to Figure 4 For reference, the present invention provides a separator. The isolation plate 1 is a thin metal plate, such as a copper thin plate. The thin metal plate 1 is roughly in the shape of a strip, and more than one hollowed-out wave-transmitting window 121 and more than one hollowed-out resonance slot 122 are arranged along the length direction of the thin metal plate 1 . Wherein, each wave-transmissive window 121 and each resonant slot 122 can be arranged correspondingly according to the formation form of the antenna array.

[0026] Specifically, each wave-transmissive window 121 is composed of more than one vertical slit 1211 formed along the height direction of the metal sheet 1. The vertical slit 1211 means that the opening direction of the slit is in the vertical direction (that is, along the height direction), ...

Abstract

The invention discloses an isolation plate, which is a thin metal plate; more than one hollow wave-transmitting window and more than one hollow-out resonant groove are arranged along the length direction of the metal plate; the wave-transmitting window consists of more than one The vertical slits are formed along the height direction of the metal sheet, and the resonant groove is composed of more than one horizontal notch processed along the length direction of the metal sheet. The invention also discloses a base station antenna. Through the above embodiments, the isolation of the low-frequency oscillator can be improved without significantly affecting the pattern of the high-frequency oscillator; and while the port isolation is improved, the sharp deterioration of the cross-polarization caused by scattering and resonance can be avoided.

Description

technical field [0001] The invention relates to a base station antenna and an isolation board thereof. Background technique [0002] Port isolation and cross-polarization discrimination are important technical indicators of base station antennas. Improving port isolation and cross-polarization discrimination is of great significance for enhancing the anti-interference ability of base station antennas, improving receiving sensitivity, giving full play to channel capacity, and increasing wireless data transmission rates. important meaning. [0003] Due to the limitation of the size of the radome and the reflector of the base station antenna, it is often difficult to achieve a safe isolation distance between the radiation units. The mutual reception and secondary radiation between the oscillators not only deteriorate the port isolation, but more seriously, secondary radiation and scattering pass through The superposition with the incident wave leads to serious deformation of t...
