Abstract

The invention relates to a load resistant microstrip antenna, comprising a radiation piece, a dielectric layer and a grounding layer which are stacked in sequence, wherein the dielectric layer comprises more than two dielectric material layers which are different in dielectric constant; and the dielectric layer comprises a first dielectric material layer contacted with the radiation piece and a second dielectric material layer contacted with the grounding layer, and the dielectric constant of the second dielectric material layer is greater than the dielectric constant of the first dielectric material layer. The load resistant microstrip antenna can improve the low-elevation gain.

Description

technical field

[0001] The invention relates to the technical field of antennas, in particular to an anti-load microstrip antenna. Background technique

[0002] During the flight, the attitude of the projectile will change. When it is launched, it is launched obliquely upward at a certain angle. After a period of time, there will be a process of level flight, and finally it will fly downward to the target at a certain angle. The entire trajectory Approximate to a parabola. The anti-load antenna is generally installed at the front end of the projectile. When the projectile rises, the anti-load antenna is obliquely upward, and it uses the forward and front side directions to receive communications from the satellites above. After that, the projectile will enter the attitude of horizontal flight, and the anti-load antenna is used to receive the navigation signal from the satellite in the sky sideways. Finally, the missile will fly obliquely downward, and the anti-load antenna...
