An antenna apparatus includes a ground layer, patch antenna patterns, feed vias, ring-type meta patterns, and coupling-type meta patterns. The ground layer has one or more through-holes. Patch antenna patterns are each disposed above the ground layer. Feed vias are disposed to penetrate through the one or more through-holes, and electrically connect to the patch antenna patterns, respectively. Ring-type meta patterns are arranged between the patch antenna patterns. Coupling-type meta patterns are alternately arranged between the patch antenna patterns in fewer numbers than the ring-type meta patterns in positions more distant from the patch antenna patterns than positions in which the ring-type meta patterns are arranged.

An antenna device includes a plurality of antenna elements, each of the plurality of antenna elements including a radiating element and at least one parasitic element. The plurality of antenna elements are arranged in a direction intersecting with an arrangement direction of the radiating element and the at least one parasitic element of at least one antenna element of the plurality of antenna elements.

The application provides an antenna and a communications device, and pertains to the field of antenna technologies. The antenna includes a horizontally polarized antenna and a vertically polarized antenna that are disposed in a superposition manner. The horizontally polarized antenna includes a metal sheet, and the metal sheet can be separately connected to a double-sided parallel strip line in the horizontally polarized antenna and a first conductor of a coaxial cable. A diameter of a maximum inscribed circle of the metal sheet is greater than a line width of the double-sided parallel strip line, and both the metal sheet and the coaxial cable are located on a first side of a substrate. Therefore, the metal sheet can effectively suppress an induced current in the coaxial cable, and impact of the induced current on the vertically polarized antenna can be reduced.

An electronic apparatus is provided. The electronic apparatus includes an integrated fan-out package, a dielectric housing, and a plurality of conductive patterns. The dielectric housing is covering the integrated fan-out package, wherein a gap or a first dielectric layer is in between the dielectric housing and the integrated fan-out package. The plurality of conductive patterns is located on a surface of the dielectric housing, wherein the plurality of conductive patterns is located in between the dielectric housing and the integrated fan-out package.

An electronic device is described. This electronic device includes: an interface circuit; and an antenna having a radiator and multiple pairs of reflectors arranged along different axes passing through the radiator in a horizontal plane. A given pair of reflectors includes reflectors on opposite sides of the radiator and along a given axis. During operation, the interface circuit provides control signals to switching elements that selectively electrically couple one or more of the reflectors in the pairs of reflectors to ground, where the one or more of the reflectors modify an antenna radiation pattern of the radiator. Then, the interface circuit communicates, via the antenna, a packet or a frame with a second electronic device, where the communication involves transmitting or receiving wireless signals corresponding to the packet or the frame.

Techniques and apparatuses are described that implement a metal structure for steering and broadening millimeter-wave (mmWave) antenna coverage. A user device includes at least one mmWave antenna that produces a near-field radiation region and a far-field radiation pattern. Disposed within the near-field radiation region is the metal structure comprising one or more metal pieces. The metal pieces are able to reflect energy associated with the far-field radiation pattern or produce another far-field radiation pattern based on currents induced in the metal pieces by the near-field radiation region in such a way that the far-field radiation pattern from the mmWave antenna is positively affected (e.g., steered and/or broadened). In this way, the far-field radiation pattern can be effectively steered and/or broadened with a simple cost and space-effective design.
