Embodiment 1

[0036] The common-aperture antenna in this implementation case is a common-aperture antenna array composed of 14 waveguide antennas 11 and 26 rows×22 columns of microstrip antennas 12. The vertical unit spacing of the waveguide antennas 11 is 21.8 mm, and the microstrip antenna 12 units are triangular grids. , the vertical unit pitch is 10.9mm, and the horizontal unit grid is 13.64mm. Each waveguide antenna 11 includes 16 radiation slots 101 . The waveguide antenna 11 and the reflection base plate 10 are made of aluminum. The thickness of the reflection base plate 10 is 0.8mm, the thickness of the waveguide wall of the waveguide antenna 11 is 0.8mm, and the right angles of the waveguide antenna 11 are treated with circular chamfering. The microstrip antenna 12 is manufactured by using double-sided copper-clad laminates through corrosion processing, and the material of the dielectric board is Rogers4003, and the thickness is 0.508mm.

Abstract

The present invention belongs to the antenna field, more specifically, relates to a common-caliber antenna formed by a waveguide antenna and a micro-strip antenna. The antenna comprises a waveguide antenna, a micro-strip antenna and a reflection baseboard, the micro-strip antenna and the waveguide antenna are respectively fixed at the upper side and the lower side of the reflection baseboard, and the reflection baseboard is provided with a waveguide antenna radiation gap. A plurality of waveguide micro-strip common-caliber antenna units are arranged side by side and combined to form an antenna array. The common-caliber antenna employs a ridge waveguide leaky antenna and a micro-strip antenna to form the common-caliber antenna, the reflection baseboard is provided with a choke groove, and the micro-strip antenna employs a back-to-back coaxial feed mode so as to eliminate the bad influence between the waveguide antenna and the micro-strip antenna and solve the integration feed problem, and therefore the reasonable layout design of the common-caliber antenna realizes the broadband wide-angle scanning capability.

Description

technical field [0001] The invention belongs to the field of antennas, and more specifically relates to a common-aperture antenna composed of a waveguide antenna and a microstrip antenna. Background technique [0002] With the continuous improvement of antenna requirements, highly integrated, wide-band and wide-angle scanning antennas are an important development direction for antenna engineering applications. The common-aperture antenna is to integrate two or more antennas into the same aperture, which can effectively reduce the area occupied by the antenna and has a high degree of integration. It is especially suitable for equipment platforms with limited area. The traditional common-aperture antenna integrates two antennas of the same system (such as a waveguide antenna and a waveguide antenna with a common aperture, and a microstrip antenna and a microstrip antenna with a common aperture). Integrating the waveguide antenna and the microstrip antenna together is extremel...
