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.

The present disclosure discloses an impedance matching component disposed between a first medium and a second medium, which is formed by stacking a plurality of homogeneous metamaterial sheet layers in a direction perpendicular to surfaces thereof. Each of the metamaterial sheet layers comprises a substrate and a plurality of man-made microstructures attached thereon. A first and last metamaterial sheet layers have impedances identical to those of the first and second media respectively. The man-made microstructures attached on the first metamaterial sheet layer have a first pattern, the man-made microstructures attached on the last metamaterial sheet layer have a second pattern, and the man-made microstructures attached on intermediate ones of the metamaterial sheet layers have patterns that are combinations of the first and second patterns, with the first pattern becoming smaller continuously and the second pattern becoming larger continuously in the stacking direction of the metamaterial sheet layers.

Impedance matching component

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.
