A quasi-omnidirectional antenna and a signal transceiver are provided. The quasi-omnidirectional antenna includes a housing having a metal rear cover facing a boundary of an installation area and a front cover disposed opposite to the metal rear cover. A forward facing antenna is disposed in the housing and is configured to radiate in a direction away from the metal rear cover. First and second side antennas are disposed in the housing, with the first side antenna and the second side antenna being oppositely disposed on two sides of the forward facing antenna. Each side antenna includes a metallic ground that is signal-connected to the metal rear cover. An overlapping area extends between the radiation area of each side antenna and a radiation area of the forward facing antenna.

An antenna device is a device of 0th-resonance antenna, which includes: a ground plate providing a ground potential; an opposed conductor arranged to have a predetermined distance from the ground plate in a plate thickness direction of the ground plate and configured for connection to a feeder line; and a short-circuit part electrically connecting the opposed conductor and the ground plate. The antenna device further includes an intermediate conductor having a same potential as the ground plate and arranged in between the ground plate and the opposed conductor in the plate thickness direction. The intermediate conductor includes a penetration part that includes the opposed conductor in a plan view in the plate thickness direction.

An antenna assembly comprises an antenna body made of metal plate, a pressing portion and a conductive film. The antenna body is provided with a pressed portion. The pressing portion presses the conductive film against the pressed portion and thereby the conductive film and the pressed portion are electrically connected to each other.

A computer mouse includes a housing. The housing includes a non-metallic base and a shell attached to the non-metallic base. The shell is formed of an electrically conductive material. The computer mouse includes a user input device in the housing. The user input device is manually operable by a user to generate a control signal. The computer mouse includes an antenna within the housing. The antenna is configured to receive the control signal from the user input device. The antenna is configured to emit a wireless signal, based on the control signal, to control operations of a computing device.

System-in-package modules that can provide a high level of functionality, are space efficient, and are readily manufactured. In an example, a high-functionality system-in-package module can include both a wireless circuit and an antenna. In an example, a space-efficient system-in-package module can include different vertical interconnect paths that can be used to connect the wireless circuit to the antenna. In an example, instead of being shaped as a traditional rectangular cuboid, a space-efficient system-in-package module can have a shape that more closely matches contours of an enclosure for an electronic device.

An electronic device is provided. The electronic device includes a communication circuit including at least one antenna, a memory, and a processor operatively connected with the communication circuit and the memory. The memory includes instructions, when executed, causing the processor to identify a communication state of the communication circuit, adjust a characteristic of the antenna to a wideband characteristic including a first wireless-fidelity (Wi-Fi) band and a second Wi-Fi band by means of the communication circuit to scan a Wi-Fi communication channel, when the identified communication state is a state where the Wi-Fi communication channel is scanned, and adjust the characteristic of the antenna to a narrowband characteristic corresponding to a determined communication channel to perform Wi-Fi communication, when the identified communication state is a state where the Wi-Fi communication channel to communicate is determined.

An integrated heatsink and antenna structure that is suitable for inclusion in small and midsized computing devices. The integrated heatsink and antenna structure may include a plurality of fin components that dissipate thermal energy integrated into a heatsink base and a plurality of radio frequency antenna portions coupled to and surrounded by the fin components. The plurality of radio frequency antenna portions may form a monopole antenna. The heatsink base may operate as a ground reference for each of the plurality of the antenna portions and to improve an omnidirectional pattern of each of the plurality of the antenna portions.

An angle-of-arrival antenna system uses two orthogonal arrays of patch antenna elements to measure the angle of arrival of a wireless signal irrespective of its polarization. Each antenna element has an antenna patch located over a corresponding ground patch. A shorting wall directly electrically connects one edge of the antenna patch to a corresponding edge of the underlying ground patch. The edge of the ground patch is also directly connected to a system ground plane. No other edges of the ground patch are connected to the system ground plane. The shorting wall acts as an impedance that isolates the ground patch from the system ground plane, and therefore improves isolation between the antenna elements. The antenna system may be constructed using conventional circuit-board fabrication techniques by implementing each shorting wall as an array of plated through-holes or slots.

The present invention provides a new wideband mm-wave end-fire magneto-electric dipole antenna with excellent beam-scanning radiation patterns and reasonably low side lobes and low cross polarizations. The antenna comprises: an asymmetrical substrate integrated coaxial line feed comprising: a first substrate having a first substrate thickness; a second substrate placed on the first substrate and having a second substrate thickness different from the first substrate thickness; a conductive signal line deposited on an upper surface of the first substrate; and two rows of waveguiding vias positioned along and at both sides of the signal line respectively; a Γ-shaped probe adopted to excite the antenna; a pair of shorted planar parallel plates serving as magnetic dipole and two pair of vertical conductive vias serving as electric dipole; and a folded vertical reflector consisting of conductive vias and strips is added to reduce the back radiation and to improve the gain of antenna.

Examples of devices having a quarter-wavelength antenna are described herein. In an example, a device may include a chassis and a quarter-wavelength antenna. The quarter-wavelength antenna includes a resonant path electrically connected the chassis.
