Embodiment Construction

[0029] With reference to the drawings and embodiments, the following provides a specific description of the technical solution of the present invention.

[0030] see figure 1 , figure 2 , the radiating unit 30 of the cross-shaped structure of the present invention comprises a symmetrical radiating arm 1, a feeding sheet 2, a feeding balun support column 3, a dielectric spacer 4, a plastic base 5 and a feeding coaxial cable 24, and the symmetric radiating arm 1 has Two pairs, two pairs of symmetrical radiation arms 1 intersect each other in a cross-shaped distribution to form a dual-polarized radiator. Each pair of symmetrical radiating arms 1 is in the shape of a 90° spread, and the center of the symmetrical radiating arms 1 is hollowed out to provide a loop groove 10 . The two symmetrical radiating arms 1 are rotationally symmetrical with respect to the center of the cross-shaped structure radiating unit 30 , so the radiators are the same for the two polarization direction...

Abstract

The invention discloses a radiating element of a cross structure and an antenna array thereof. The radiating element comprises symmetrical radiating arms, feed sheets, medium gaskets, a feed balun supporting column, a plastic base and coaxial feed cables, and array antennas composed of the radiating elements are involved. The two symmetric radiating arms are distributed in a cross shape and are rotationally symmetric about the center of the radiating unit; the medium gaskets are feed sheet supporting parts and separate the feed sheets from the feed balun supporting column; the feed balun supporting column supports and is connected with the symmetrical radiating arms; the plastic base is arranged at the lower end of the feed balun supporting column and used for insulating the feed balun supporting column from an outer reflecting plate, and the coaxial feed cables are connected with the feed sheets through the plastic base. The antenna array is an antenna system formed by linearly arranging multiple identical radiating elements of the cross structure at equal interval. The radiating element is small in size, wide in bandwidth and high in intermodulation stability.

Description

technical field [0001] The invention relates to the field of mobile communication base station antennas, and mainly includes a cross-shaped structure radiation unit and an antenna array using the radiation unit. Background technique [0002] In recent years, mobile communication technology has developed rapidly, and there are more and more occasions where communication systems of various standards coexist. Since communication systems of various standards have various working frequency bands, and with the gradual promotion of mobile communication systems, The operating frequency band of the communication system is further expanded, which makes the mobile communication system require a wider antenna frequency band. [0003] In addition, in order to save base station installation resources and reduce the cost of network construction, the communication system solution integrating multiple standards has received more and more attention and is widely used. The CDMA 800MHz and GSM...
