Problems solved by technology

The equivalent magnetic dipole of a slotted antenna has a planar structure as a radiating element, which is conducive to conformality, but it is difficult to place two slotted antennas in the same plane to achieve dual polarization
In addition, the profile of the antenna is also high, it is difficult to apply to some small wings

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the implementation methods and accompanying drawings.

[0033] The wing-borne dual-polarization strongly coupled ultra-broadband dipole conformal phased array of this embodiment adopts the array form of 1×16, such as image 3 shown. Its basic antenna elements such as figure 1 , 2 shown. The curved metal floor (100) is formed by bending a whole piece of thin aluminum plate to fix and support the antenna, and at the same time reflect the energy radiated backward by the antenna to increase the gain and directivity of the antenna. The floor is perforated in specific places, and the coaxial inner core passes through the holes and connects with the balun metal feed. The traditional marchand balun (102) is used for feeding horizontally polarized dipoles, and plays the role of impedance transfor...

Abstract

The invention discloses a thin wing conformal dual-polarization strong coupling ultra-broadband dipole phased array and a development method thereof. Aiming at the special carrier that needs conformality, based on the dual-polarization strong-coupling array antenna, a thin wing conformal dual-polarization strong-coupling ultra-broadband dipole phased array is designed. The entire phased array antenna structure has been conformally processed. From the bottom curved metal floor to the outermost antenna protection layer, the partial wing is used as the carrier, which will not affect the aerodynamic layout of the flying wing. The invention can realize ±45° scanning in the antenna array direction in the 0.5-2GHz (4:1) frequency band, and the profile height is only 0.3 high-frequency wavelengths, and is suitable for application platforms requiring dual polarization, ultra-wideband and conformal.

Description

technical field [0001] The invention belongs to the technical field of antenna engineering, and in particular relates to an ultra-wideband phased array conformal antenna based on a strong mutual coupling effect and a development method thereof. Background technique [0002] With the increasing development of the electronic information industry, especially the military electronic information has more and more stringent requirements on the performance of the antenna, the traditional mechanical scanning antenna can no longer meet the demand. A new type of array antenna, which achieves the purpose of beam scanning by changing the feeding phase of the unit, came into being. Compared with traditional mechanical scanning arrays, phased arrays have many advantages such as more flexible and changeable beams, faster and more accurate beam scanning capabilities, and are therefore widely used in many military and civilian fields such as communications, radar, and electronic countermeasu...
