Abstract

The invention provides a miniaturized high-gain metamaterial horn antenna. The miniaturized high-gain metamaterial horn antenna comprises a horn antenna body, the horn antenna body is provided with a step hole which extends inwards from an output port surface, the interior of the step hole is fixedly provided with a phase distribution regulation module which is used for making electromagnetic waves in the output port surface in uniform phase distribution; the phase distribution regulation module comprises at least two inhomogeneous metamaterial metal sheets which are arranged in an overlapping mode, a metallic gasket is arranged between two adjacent inhomogeneous metamaterial metal sheets, and the outer side surface of each outermost inhomogeneous metamaterial metal sheet is flush with the output port surface. According to the miniaturized high-gain metamaterial horn antenna, miniaturization, light weight and integration of the horn antenna can be guaranteed on the premise that high far-field benefit is achieved.

Description

technical field [0001] The invention relates to the technical field of millimeter wave antennas, in particular to a miniaturized high-gain metamaterial horn antenna. Background technique [0002] Antennas are indispensable devices in modern communication systems and radar systems. Among them, the horn antenna is the most common form, because of its simple design, high power capacity, and low return loss, it is especially suitable for high-frequency and high-power systems. However, with the rapid development of modern communication technology and radar systems, higher requirements are placed on the performance of horn antennas. For example, the size of the horn antenna is required to be reduced while its far-field gain remains unchanged, that is, the horn antenna is required to be more miniaturized, lightweight, and integrated. At the same time, higher requirements are put forward for the cost control of the horn antenna. With the in-depth study of metamaterials in the sci...
