Abstract

The application relates to a Ku-band low-profile panel antenna, which mainly includes: a horn radiation layer, a microstrip feed layer, a transmission layer, and a reflection layer. The horn of the horn radiation layer is trapezoidal, and each layer of the antenna is screwed. connect. The horn radiation layer adopts a trapezoidal design, which can improve the radiation performance of the antenna. The various layers of the antenna are connected by screws, which can ensure that the relative positions of each layer will not shift, and ensure the performance of the antenna. The processing is relatively simple and the cost is low. The antenna efficiency is high, up to about 85%, the antenna pattern is highly equalized, the antenna profile is low, the antenna height is about 23.7mm, the antenna is light, the weight is about 0.9kg, it is easy to carry and store, and it is easy to assemble into a higher gain antenna. The antenna adopts a symmetrical array structure, and the cross-polarization performance is relatively ideal.

Description

technical field [0001] This application relates to the field of satellite communication antennas, in particular to a Ku-band low-profile panel antenna. Background technique [0002] With the development of the satellite communication industry, the requirements for satellite communication antennas are getting higher and higher, which require the advantages of light weight, low profile, high performance, and portability. Due to its own structural characteristics, the traditional parabolic antenna cannot be small in size, and the parabolic antenna has relatively high precision requirements. Therefore, it is impossible to split the antenna surface into many parts for the parabolic antenna, and it is very difficult for the operator. The technical requirements of the antenna are relatively high. If the assembly accuracy is not up to standard, the performance of the antenna will also be substandard. Vehicle-mounted antennas and airborne antennas have strict requirements on the hei...
