Embodiment Construction

[0032] Below in conjunction with specific embodiments, the present invention will be further illustrated, and it should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. The modifications all fall within the scope defined by the appended claims of this application.

[0033] like Figure 1-5 As shown, the dual-polarized integrated planar lens antenna is a layered structure, and is provided with a planar lens 1, a secondary feed source 2, a dual-polarized primary feed source 3 and a metal antenna bracket 4 for supporting in sequence from top to bottom.

[0034] The plane lens 1 is square, with side length L1 and thickness H1. Several non-metallized holes 11 are arranged on the plane lens. The arrangement of the non-metallized holes is determined by the phase compensation distribution and the unit phase compensation capability.

[0035] The phase to be compensated can be calculated by the f...

Abstract

The invention discloses a dual polarization integration plane lens antenna. The antenna which is in a layered structure is sequentially provided with a plane lens, a secondary feed source and a dual polarization primary feed source; a metal antenna support is arranged on the exterior. According to the dual polarization integration plane lens antenna which is based on a plane substrate integration waveguide structure, a substrate integration waveguide cavity antenna serves as a dual polarization feed source to perform feed on the secondary feed source, the secondary feed source and the primary feed source form into an equivalent feed source to feed the plane lens commonly, phase compensation is obtained from the lens, spherical waves are converted to be plane waves, and accordingly the antenna with high gain, high efficiency and stable pointing direction is achieved. The antenna aiming at development requirements of plane integration and a minimized long-distance wireless communication system with high gain, allows dual polarization and is low in profile, easy to integrate with a millimeter wave circuit is achieved under the Q-LINKAN application background. The dual polarization integration plane lens antenna has the advantages of being simple in design, firm in structure, compact in size and being capable of being integrated with the plane circuit.

Description

technical field [0001] The invention relates to a dual-polarization integrated plane lens antenna, which belongs to the technical field of communication. Background technique [0002] As an important part of the communication system, the antenna has a great influence on the performance of the whole system. Millimeter-wave antennas are different from RF antennas in design due to smaller physical size and higher metal losses. At present, the research on millimeter-wave antennas at home and abroad mostly focuses on the Ka-band for satellite antennas, the 57-66 GHz frequency band for millimeter-wave communications in the West, and the E-band for imaging, while the Q-band antennas There are few studies, and the products on the Q-band are basically blank. [0003] In the millimeter-wave frequency band, the dielectric loss of the substrate and the metal loss caused by the metal layer become considerable. The method of increasing the gain by increasing the number of array element...
