Abstract: An automated medicament delivery device for automated administration of medicament to a user-body is disclosed. The automated medicament delivery device includes a delivery system, a printed circuit board (PCB), and an off-board antenna. The delivery system configured to deliver medicament to the user-body. The PCB comprising a PCB connection. The off-board antenna including an elevation portion. The elevation portion generally extends in a direction transverse to a plane defined by a surface of the PCB. The elevation portion includes a connection end in contact with the PCB connection electrically connecting the off-board antenna to the PCB. An upper portion secured to at least one support element chosen from a chassis and a housing of the automated medicament delivery device.

Abstract: Methods and systems for controlling an antenna array of an automated medicament delivery device are disclosed. The method includes causing the antenna array to transition between multiple array configurations. The multiple array configurations are chosen from among configurations that vary at least one characteristic of a signal emitted or received by one or more antennas of the antenna array, configurations that vary an activation status of the plurality of antennas, and configurations that vary a combination of the at least one characteristic of a signal and an activation status of the plurality of antennas. The method also includes measuring a power of a received signal for each configuration of the multiple array configurations of the antenna array. The method further includes selecting an array configuration of the multiple array configurations based at least in part on results of the measuring and setting the antenna array to the array configuration selected.

Abstract: An automated medicament delivery device for automated administration of medicament to a user-body is disclosed. The automated medicament delivery device includes a delivery system, a housing, a printed circuit board (PCB), one or more antennas, an adhesive liner, and a reflective ground shield. The delivery system is configured to deliver medicament to the user-body. The housing is configured to enclose multiple components therein. The PCB is within the housing. The one or more antennas are connected to the PCB. The adhesive liner comprises a flexible substrate and an adhesive configured to secure the housing to a user-body. The reflective ground shield is between the PCB and the adhesive, the reflective ground shield being physically separated from the one or more antennas.

Abstract: A slot antenna is disclosed. The slot antenna structure includes a dielectric substrate, a grounding plate and a resonator. The grounding plate is disposed over a first side of the dielectric substrate and defines a slot. The feeding strip is disposed over a second side of the dielectric substrate and opposite to the grounding plate. The resonator is coupled to the grounding plate and is disposed horizontally within the slot.

Abstract: An antenna structure and an antenna array are disclosed. The antenna structure includes first and second feeding traces, first to fourth vias and a radiator. The first feeding trace has a first meander portion that generates a 180-degree phase change along a length thereof at an operation frequency of the antenna structure. The second feeding trace has a second meander portion that generates a 180-degree phase change along a length thereof at the operation frequency of the antenna structure. The first and second vias are respectively coupled to two opposite points of the first feeding trace with respect to the first meander portion. The third and fourth vias are respectively coupled to two opposite points of the second feeding trace with respect to the second meander portion. The radiator coupled to the first to fourth vias. The antenna array includes antenna cells each with the antenna structure.

Abstract: The disclosure relates to technology for testing parameters of an antenna under test. The technology includes an antenna test bed, reference antenna and turntable for supporting the device and antenna under test. The turntable may be used to test the response of the antenna under test at different azimuth angles. Additionally, the reference antenna and turntable are integrated into a single test bed platform to ensure consistency and repeatability of test results.

Abstract: A phase shifter circuit and a power divider are disclosed. The phase shifter circuit provides a (90/N)-degree phase shift for a signal with two or more frequencies, where N is an integer. The phase shifter circuit includes a first inductor, a first capacitor, a second inductor and a second capacitor. The first inductor is grounded, and is coupled to the first capacitor in series. The second inductor is grounded, and is coupled to the second capacitor in series. A first node between the first capacitor and the first inductor is coupled to a node between a second node between the second capacitor and the second inductor. The power divider includes plural circuit blocks cascaded in series. Each circuit block provides a (90/N)-degree phase shift for a signal with two or more operating frequencies.
