Embodiment Construction

[0018] In order to make the objects, technical solutions, and advantages of the present invention, the present invention will be further described in further detail below in connection with the drawings.

[0019] A total medium integrated planar ultra-wideband low cross-section wide angle scanned phase-controlled array antenna, which is 12 × 12.12 antenna unit is arranged in the X direction, and the unit spacing is 12mm, 12 antenna unit Along the Y direction, the unit spacing is 12 mm. Such as figure 1 As shown, the lowermost metal floor 107 is included. The four-layer antenna dielectric substrate 103, 104, 105, 106. The relative dielectric constant of the four-layer medium is 2.2, and its thickness is 0.5 mm, 2 mm, 2 mm, 2 mm, respectively. The coupling adhesive arms 114 and 117 are printed on the surface of the dielectric substrate 103, wherein the dipole arm 114 has a front end width of 1 mm, a terminal width of 3 mm, and a length of 5.4 mm. The dipole arm 117 has a front end w...

Abstract

The invention discloses an all-dielectric integrated planar ultra-wideband low-profile wide-angle scanning phased array antenna, which belongs to the technical fields of radar technology and antenna engineering. The invention includes the bottom metal floor, four layers of antenna dielectric substrate, three layers of prepreg connected to the antenna dielectric substrate, and two layers of dielectric substrate for wide-angle impedance matching. Additional loading coupling patch structures and short-circuit probes eliminate the need for The common-mode resonance in the antenna band realizes the large-angle scanning performance of the antenna under ultra-wideband, and because it is a multi-layer PCB with a planar structure that can be modularized, it has the advantages of convenient processing, simple structure, easy assembly, and easy integration. The advantages of high shape and mechanical strength. And there is no need to design a complicated feed network.

Description

Technical field [0001] The present invention belongs to the field of radar technology, and the antenna engineering technology. In the radar and communication system such as millimeter wave. Background technique [0002] The phase-controlled array antenna technology is widely used in various radar systems, which has a fast wide-angle scan without a moving antenna; adaptive beamforming; multi-beam; distributed diameter; low radar scattering section; The overall work performance change is small. The radar system using the phase-controlled array antenna can intelligently implement the beam scan in the large airspace, acquire the target information in the set airspace, change the antenna beam and point to the shape, short reaction time, high data rate, can be allowed to the whole space Each frequency band electromagnetic wave is transmitted and received, and the exact completion of the tasks such as search, tracking, capture, and identification of multiple objects is performed. [000...
