An antenna structure includes a metal housing, a first feed source, and a first radiator. The metal housing includes a front frame, a backboard, and a side frame. The side frame defines a slot and the front frame defines a gap. The metal housing is divided into at least a long portion and a short portion by the slot and the gap. The first radiator is positioned in the housing and includes a first radiating portion and a second radiating portion. One end of the first radiating portion is electrically connected to the first feed source and another end of the first radiating portion is spaced apart from the long portion. One end of the second radiating portion is electrically connected to the first feed source and another end of the second radiating portion is spaced apart from the short portion.

The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. An antenna module is provided. The antenna module includes a flexible printed circuit board (FPCB) including a first surface directed in a first direction and a second surface directed in a second direction that forms a predetermined first angle with respect to the first direction, a first antenna deployed on one surface of the first surface, and a second antenna deployed on one surface of the second surface.

An antenna apparatus having an antenna. The antenna comprises a first radiator section and a second radiator section coupled to each other, and a third radiator section, a fourth radiator section, and a fifth radiator section that are distributed on a same side of the first and second radiator sections, wherein the third radiator section is coupled to a junction of the first and second radiator sections and is grounded, and the fourth and fifth radiator sections are separately disposed on two sides of the third radiator section, wherein the fourth radiator section is grounded by a first switch, and the fifth radiator section is grounded by a second switch.

A Bluetooth earphone includes an antenna and a circuit board. The circuit board includes a first grounding branch and a second grounding branch. The first grounding branch is connected in series to a first switch, and the second grounding branch is connected in series to a second switch. When the first switch is on, the first grounding branch serves as a current return path of the antenna. When the second switch is on, the second grounding branch serves as a current return path of the antenna. By controlling the on or off state of the first switch and the second switch, the Bluetooth earphone can switch ground structures of the antenna and select different current return paths for the antenna, to switch radiation patterns of the antenna.

Various embodiments provide systems, devices, and methods for an antenna assembly included in an integrated circuit (IC) package. The antenna assembly may be used for near field wireless communication such as package-to-package and/or chip-to-chip communication. The antenna assembly may include a feed plate (e.g., a top feed) that is capacitively coupled to a first via and a second via. The feed plate may further be capacitively coupled to a loading structure. The first via may be conductively coupled to a ground potential. In some embodiments, the antenna assembly may further include a stub structure (e.g., an open stub or a short stub) that is conductively coupled to the second via. An impedance matching network may be coupled between the feed plate and an IC die that communicates using the antenna assembly. Other embodiments may be described and claimed.

A multi-input multi-output (MIMO) antenna system includes a metal plate, a background scanning antenna, a plurality of working antennas, and an isolator module. The isolator module is mountable on the metal plate and includes a plurality of isolators that are in a ring configuration to form an isolated space therein, so that the background scanning antenna can be located in the isolated space and a plurality of working antennas are located outside of the isolated space, thereby ensuring good isolation of the background scanning antenna from the working antennas by the design of the isolator module.
