摘要： An impedance matching component is disclosed. The impedance matching component is disposed on and closely attached to a first side surface of a function dielectric sheet. The impedance matching component comprises a first plurality of impedance matching layers, each of which has a refractive index distribution represented as follows: n i r = n min × n g r n min i c + 1 ; where, i represents a serial number of each of the impedance matching layers and is a positive integer; n i ( r ) represents refractive indices of points in the i th impedance matching layer that have a distance of r from a center of the i th impedance matching layer; n g ( r ) represents refractive indices of points in the function dielectric sheet that have a distance of r from a center of the function dielectric sheet; n min represents the minimum refractive index of the function dielectric sheet; and c represents the number of the impedance matching layers. The present invention further discloses a metamaterial panel, a converging component and an antenna. According to the impedance matching component, the metamaterial panel, the converging component and the antenna of the present invention, the reflection interferences and losses are further reduced by designing the refractive index distribution of each of the impedance matching layers. Thus, the energy consumption of the electromagnetic waves when propagating into the function dielectric sheet is reduced, which facilitates further transmission of the electromagnetic waves.

摘要： The present invention provides a reflective array surface. The reflective array surface includes a functional board that is configured to perform beam modulation on an incident electromagnetic wave and a reflection layer that is disposed on one side of the functional board and is configured to reflect an electromagnetic wave, where the functional board includes two or more functional board units and the reflection layer includes reflection units, where the number of reflection units corresponds to the number of functional board units, where the functional board unit and a reflection unit corresponding to the functional board constitute a phase-shifting unit that is used for phase shifting. According to the reflective array surface in the present invention, a functional board unit and a reflection unit corresponding to the functional board unit constitute a phase-shifting unit that is used for phase shifting, which can solve a problem in the prior art that a phase-shifting effect is not exquisite enough and a beam modulation capability for an electromagnetic wave is poor, thereby affecting bandwidth and working performance of a reflective array antenna. In addition, the present invention further provides a reflective array antenna.

摘要： The present invention relates to an antenna reflector phase correction film and a reflector antenna. The antenna reflector phase correction film includes a first substrate, a second substrate, and multiple artificial microstructures disposed between the first substrate and the second substrate, the artificial microstructures are wires made of electrically conductive materials, and an electromagnetic wave, emergent after being reflected by an antenna reflector attached with the antenna reflector phase correction film, has an equiphase surface. According to the present invention, the antenna reflector phase correction film has specific refractive index distribution internally, so that a surface emergent phase of a reflector can be corrected after attaching onto a surface of a conventional reflector, a phase error caused due to installation or processing is improved, a complete flat emergent equiphase is obtained, and then a far-field performance (such as a higher gain) is improved.

摘要： The disclosure discloses a Cassegrain-type metamaterial antenna, including: a metamaterial main reflector having a central through-hole, a feed source disposed in the central through-hole, and a sub-reflector disposed in front of the feed source, where an electromagnetic wave radiated by the feed source is emerged in a form of a plane wave after being reflected by the sub-reflector and the metamaterial main reflector in sequence; the metamaterial main reflector includes: a first core layer and a first reflection layer disposed on a rear surface of the first core layer, where the first core layer includes at least one first core layer lamella, and the first core layer lamella includes: a first base material and multiple first conductive geometric structures disposed on the first base material; and a far focus of the sub-reflector coincides with a phase center of the feed source. According to the Cassegrain-type metamaterial antenna in the disclosure, a conventional paraboloid is replaced with a lamellar metamaterial main reflector, which allows for easier manufacturing and processing and lower costs.
