Integrated modulatable metamaterial radome and antenna assembly

Abstract

The invention discloses an integrated modulatable metamaterial radome and an antenna assembly. A high-gain antenna and the metamaterial radome are comprised; the metamaterial radome is formed by superposing and fixing three layers of array metamaterial plates; each array metamaterial plate is composed of a dielectric plate and metamaterial units; the metamaterial units are evenly distributed on the dielectric plate from top to bottom and from left to right to form an N * N array, and N is larger than or equal to 7; each array metamaterial plate is a zero-refractive-index metamaterial plate; the high-gain antenna is a microstrip patch antenna with a working frequency band of 10GHz; each metamaterial unit is of an I-shaped metal structure with two ends bent inwards, the length and the widthof each metamaterial unit are both 5mm, and the bending length of each metamaterial unit is 1.85 mm. The gap between the upper metamaterial unit, the lower metamaterial unit, the left metamaterial unit and the right metamaterial unit which are adjacent in each array metamaterial plate is 0.4 to 0.6 mm, the distance between the high-gain antenna and the metamaterial radome is 21 to 25 mm; the gainof the microstrip patch antenna reaches 9.572 dBi; and high-efficiency transmission is achieved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication and electromagnetic shielding in aircraft platform cabins, and relates to an integrated modulating metamaterial radome and antenna assembly. Background technique [0002] At present, the internal communication of most aircraft still relies on various conventional cable equipment to transmit digital information and control signals, and the data communication cable inside the aircraft is used for communication. 10% to 15% of the weight, these will cause a heavy burden and cost waste to the flight tasks of various aircraft. In order to avoid the heavy burden and waste of cost caused by the data communication cables, fixing parts, connectors and other auxiliary devices inside the aircraft to the flight tasks of various aircraft, various research institutions at home and abroad are actively developing the internal communication cables of the aircraft. To reduce the burden, such as using...
