Abstract

The invention relates to the technical field of microstrip antennas, in particular to a three-dimensional SRRs-based metamaterial microstrip antenna and a manufacturing method thereof. The three-dimensional SRRs-based metamaterial microstrip antenna comprises an antenna pattern, a plurality of inner dielectric layers, a plurality of three-dimensional SRRs pattern units and a bottom microwave ground, the dielectric component is internally provided with plated-through holes used for placing a plurality of three-dimensional SRRs pattern units, the number of groups of the three-dimensional SRRs pattern units is matched with the number of antenna oscillators of the microstrip antenna, the plurality of three-dimensional SRRs pattern units are arranged into an array structure to form a three-dimensional SRRs pattern array, the upper surface of the dielectric component is coated with an antenna pattern, each three-dimensional SRRs pattern unit is internally provided with at least one three-dimensional SRRs pattern piece. The microstrip antenna based on the three-dimensional metamaterial is excellent in electrical performance index and can be used in a microwave frequency band of 76-77GHz and below, the bandwidth is -10dB, the size of an antenna patch pattern can be reduced to 25% or below of the original size, and the maximum gain is 4.5 dB.

Description

technical field [0001] The invention relates to the technical field of microstrip antennas, in particular to a microstrip antenna based on three-dimensional SRRs metamaterials and a manufacturing method thereof. Background technique [0002] Microstrip antennas have the characteristics of light weight, small size, low profile, easy integration, and flexible feeding. They are widely used in satellite systems, radar systems, countermeasure communications, and space vehicle design. The microstrip antenna is divided into feed network, radiating element and radiating background. However, the gain of a single microstrip antenna is low, there are dielectric loss and surface wave loss, and the radiation efficiency is low. When it is applied, more elements are required to form a large planar array antenna, which leads to a complex feeding network and larger feeder loss. It will cause a significant drop in antenna efficiency. The smaller the size of the traditional antenna, the smal...
