摘要： The present disclosure discloses an antenna device, which comprises an array antenna and a power divider. The array antenna comprises a plurality of antenna units, and each of the antenna units comprises a conductive sheet engraved with a groove topology pattern, conductive feeding points and a feeder line. The power divider is adapted to divide a baseband signal into a plurality of weighted signals and then transmit the weighted signals to the antenna units arranged in an array via the conductive feeding points respectively. By arraying the antenna units and using the beam forming method, the directionality of the antenna can be designed as needed through phase superposition between the antenna units; and then, a reflective metal plate is provided on the back side of the antenna so that a back lobe of the antenna is compressed. In this way, the miniaturized antenna array can obtain a high directionality so as to replace the conventional indoor directional antennae.

摘要： Embodiments of the present disclosure relate to an impedance matching component and a hybrid wave-absorbing material. The impedance matching component is disposed between a first medium and a second medium, and comprises a plurality of functional sheet layers. Impedances of the functional sheet layers vary continuously in a stacking direction of the functional sheet layers, with the impedance of a first one of the functional sheet layers being identical to that of the first medium and the impedance of a last one of the functional sheet layers being identical to that of the second medium. According to the impedance matching component and the hybrid wave-absorbing material of the present disclosure, the impedance matching component has a graded impedance, with an impedance value thereof at a side being identical to that of a first medium and an impedance value thereof at the other side being identical to that of a second medium. The continuous changes in the intermediate portion eliminate sudden transitions of the impedance between the first medium and the second medium. Thereby, the problems of partial reflection and energy loss of electromagnetic waves when propagating through an interface between different media are overcome. Furthermore, the hybrid wave-absorbing material of the present disclosure has improved wave-absorbing performances.

摘要： The present disclosure relates to a depolarizer based on a metamaterial, which comprises a plurality of sheet layers parallel with each other. Each of the sheet layers has a sheet substrate and a plurality of man-made microstructures attached on the sheet substrate. The sheet substrate is divided into a plurality of identical unit bodies. Each of the unit bodies and one of the man-made microstructures that is attached thereon form a cell that has an anisotropic electromagnetic property. Each of the sheet layers has at least two cells whose optical axes are unparallel with each other. According to the depolarizer based on a metamaterial of the present disclosure, at least two cells whose optical axes are unparallel with each other are disposed in each of the metalmaterial sheet layers. Therefore, when an electromagnetic wave having a uniform polarization property propagates through the metamaterial, at least part of the electromagnetic wave will be changed in polarization property, thus achieving the purpose of depolarization. Moreover, as compared to the prior art, the depolarizer of the present disclosure features a simple structure and is easy to be implemented.

摘要： A metamaterial for separating an electromagnetic wave beam is disclosed. Two kinds of man-made microstructures are attached on a substrate of the metamaterial. The first man-made microstructures each have a principal optical axis parallel to a first electric field direction, and the second man-made microstructures each have a principal optical axis parallel to a second electric field direction. The metamaterial comprises a first region and a second region. The first man-made microstructures in the first region have the largest geometric size and the first man-made microstructures in other regions increase in geometric size continuously in a direction towards the first region; and the second man-made microstructures in the second region have the largest geometric size and the second man-made microstructures in other regions increase in geometric size continuously in a direction towards the second region. By virtue of the principal that responses of the man-made microstructures to the electric fields are related to structures thereof and the principle that an inhomogeneous metamaterial can deflect electromagnetic waves, the metamaterial of the present disclosure can separate an incident electromagnetic wave beam, flexibly control exiting angles of the separated electromagnetic waves and allow for separation of a large-area electromagnetic wave beam.

摘要： An antenna comprises a medium substrate and grounding units attached on the medium substrate. The antenna further comprises a metal structure attached on the medium substrate. The metal structure comprises an electromagnetic response unit, a metal open ring enclosing the electromagnetic response unit and a feeding point connected to an end of the metal open ring. The electromagnetic response unit comprises an electric-field coupling structure. This design increases the physical length of the antenna equivalently, so an RF antenna operating at an extremely low frequency can be designed within a very small space. This can eliminate the physical limitation imposed by the spatial area when the conventional antenna operates at a low frequency, and satisfy the requirements of miniaturization, a low operating frequency and broadband multi-mode services for the mobile phone antenna. Meanwhile, a solution of a lower cost is provided for design of the antenna of wireless communication apparatuses.
