Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. It is not intended to indicate or imply that the referred device or element must have a particular orientation, be constructed in a particular orientation, and operate in a particular orientation, and thus should not be construed as limiting the invention.

[0033] Such as figure 1 As shown, a reconfigurable ultra-wideband array antenna includes a dielectric substrate 1, and the upper surface of the dielectric substrate 1 is provided with 9 dual-polarized planar dipole antenna units 2, and 9 dual-polarized planar dipoles The ant...

Abstract

The invention discloses a reconfigurable ultra-wideband array antenna. Nine dual-polarization planar dipole antenna units are distributed on a dielectric substrate in three rows and three columns, andeach dual-polarization planar dipole antenna unit comprises two feed ports and four metal patches located around the feed ports. The two transverse metal patches and the two longitudinal metal patches are respectively connected through a feed port. In the second line, except for the two middle adjacent transverse metal patches, switches are arranged between the other two adjacent transverse metalpatches; in the second column, except for two middle adjacent longitudinal metal patches, switches are arranged between the other adjacent longitudinal metal patches. A capacitive coupling metal sheet is arranged on the lower surface of the dielectric substrate, and the capacitive coupling metal sheet is located below the two metal patches, close to each other, between the two adjacent dual-polarization planar dipole antenna units. The antenna has the advantages that the bandwidth of the antenna can be reconstructed with the number of times as small as possible, and the requirement of an ultra-wideband system for the antenna is met.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a reconfigurable ultra-wideband array antenna. Background technique [0002] As more and more radar, electronic warfare, communication, navigation and other functions need to be implemented on spaceborne, spherical, airborne and shipborne platforms, the number of antennas on each platform has increased significantly. This creates problems including mutual antenna interference, electromagnetic interference and increased radar scatter area, as well as maintenance issues associated with multiple systems. The increasing functional requirements of the above-mentioned systems put forward higher requirements on the precious antenna resources of the existing platforms. The integrated radio frequency system of various equipment platforms, including electronic countermeasures, requires the antenna units and arrays in the system to share the aperture. In order to meet the design requirements of mo...
