An on-body drug delivery device may have one or more antennas secured outside a housing of the on-body drug delivery device for facilitating wireless communications. The one or more antennas may be secured to an adhesive pad that adheres the on-body drug delivery device to a user. Alternatively, the one or more antennas may be secured to a portion of the housing for the on-body drug delivery device. In such instances, the one or more antennas may pass through one or more holes in the housing to facilitate an electrical connection with a component, like a wireless communications transceiver, inside the housing. Alternatively, wireless communications with the one or more antennas and the component may be used.

An antenna device and an electronic device including the same are provided. The antenna device includes a housing that includes a first plate, a second plate facing a direction opposite to the first plate, and a side member surrounding a space between the first plate and the second plate, a display viewable through at least a portion of the first plate, an antenna assembly disposed within the housing wherein the antenna assembly includes a first printed circuit board, a second printed circuit board, at least one structure interconnecting the first printed circuit board and the second printed circuit board and including conductive paths, a plurality of conductive patterns, and a wireless communication circuit, a flexible printed circuit board, and a third printed circuit board.

An antenna assembly according to the invention includes a universal whip mount for mounting one of a variety of antenna whips to the antenna assembly, a loading coil inductor and a circuit board having a combination of both fixed and variable capacitors. The antenna assembly of the invention can be tuned to a wide range of frequencies with minimal disassembly and without soldering.

An outer space deployable antenna may include a waveguide antenna feed section. A first plurality of wires and a first plurality of biased hinges may couple the first plurality of wires together to be self-biased to move between a collapsed stored configuration and an extended deployed configuration. A horn antenna section may be coupled to the waveguide antenna feed section and may include a second plurality of wires and a second plurality of biased hinges coupling the second plurality of wires together to be self-biased to move between the collapsed stored configuration and the extended deployed configuration. A flexible electrically conductive layer may cover the waveguide antenna feed section and the horn antenna section in at least the extended deployed configuration.

Systems and methods described herein include collapsible and deployable antenna structures including shape memory composite components.

An antenna for a portable communication device is provided. The antenna comprises an antenna body having an upper section and a lower section with a connection point therebetween. The connection point being configured to: couple the upper and lower sections during normal antenna operation; decouple the upper and lower sections in response to an impact event; and recouple the upper and lower sections after the impact event.

Embodiments of the present disclosure relate to a biconical antenna assembly for electromagnetic compatibility testing. The biconical antenna assembly has an antenna feeding point, a first antenna structure and a second antenna structure. The first antenna structure and the second antenna structure extend from the antenna feed point towards opposite directions. The biconical antenna assembly includes at least one additional capacitive structure that is attached to a most distal point of the first antenna structure or the second antenna structure from the antenna feed point.

A radio-frequency device includes a radio-frequency module. The radio-frequency module includes a first substrate, a second substrate, a radio-frequency integrated circuit (RFIC), a front-end integrated circuit (FEIC), and a flexible substrate. The RFIC has at least a portion surrounded by a first core member and is configured to input or output a base signal and a first radio-frequency (RF) signal having a frequency higher than a frequency of the base signal. The FEIC has at least a portion surrounded by a second core member and is configured to input or output the first RF signal and a second RF signal having a power different from a power of the first RF signal. The flexible substrate is configured to connect the first and second substrates to each other, provide a transmission path for the first RF signal, and being more flexible than the first and second substrates.
