Problems solved by technology

[0005] Although the microstrip conformal antenna has so many excellent characteristics, due to its complex shape, people's research on the microstrip conformal antenna is still concentrated on the microstrip antenna array.
The synthesis of conformal arrays is a complex system problem. Considering the influence of many factors in array synthesis, it is difficult to have a strict and precise solution to this problem
There is the same shortcoming in its design method and the design method of above patent

Abstract

The invention discloses a large K-waveband conformal antenna array plane and aims to provide a conformal phased array antenna array plane which does not generate a frequency deviation or a relatively high derotation component, and has a good broadband wide-angle scanning gain characteristics and good broadband wide-angle scanning circular polarization characteristics. The large K-waveband conformal antenna array plane is realized through the following technical scheme: conductor patches are divided into four groups and are arranged on an upper surface of a lower dielectric substrate in a form of a quadrant sequence rotation array, and projections of feeding points of a micro-strip patch antenna on a plane plate are arranged triangularly; the conductor patches are sandwiched between an upper dielectric substrate and the lower dielectric substrate; a radio frequency coaxial connector sequentially passes through the plane plate, a metal cone and the lower dielectric substrate to jointly form the micro-strip patch antenna; the radio frequency coaxial connector carries out coaxial probe feeding on the micro-strip patch antenna; and a pair of orthogonal polarization degenerate modes which have equal amplitudes and a phase difference of 90 degrees are excited on the conductor patches to form the conformal phased array antenna array plane for radiating right-handed circular polarization electromagnetic waves.

Description

technical field [0001] The invention relates to a large-scale K-band conformal antenna array with an aperture greater than or equal to 16 working wavelengths and a preparation method thereof. Background technique [0002] Large area antennas have high gain, low noise radiation, high reliability and strong data transmission capability, so they are widely used in modern satellite communication systems, space science and other fields. With the rapid development of modern wireless communication, the requirements for antenna performance are getting higher and higher. Whether it is in the field of military defense or civil communication, more stringent requirements are put forward for the impedance bandwidth, pattern, polarization, gain characteristics and reliability of the antenna system of the antenna. It is easier to obtain these characteristics by using different forms of array antennas. [0003] Due to the inertia of the traditional fixed-beam mechanical scanning array ant...
