摘要： A method is provided for designing an antenna comprising: i) determining dimensions of a fractional-mode, FM, air-filled, AF, antenna cavity, a FM-AF cavity, resonating around a target centre frequency characterized by a conductive ground cavity layer, a conductive top cavity layer, conductive cavity sidewalls between the top and ground cavity layer, and a side opening resulting from the fractional-mode; ii) adding a guard trace for shielding radiation from the side opening by adding sidewalls at a distance from the side opening; wherein the conductive top cavity layer is at least partially open over said distance thereby obtaining a radiating slot between the guard trace and the FM-AF cavity; wherein the FM-AF cavity and radiation slot forms an antenna cavity; iii) matching the impedance of the antenna cavity around the target centre frequency by adjusting the FM-AF and/or radiating slot dimensions within a maximum footprint.

摘要： An electronic device and an antenna module are provided. The electronic device includes a metal housing with a slot having an open end and a first upper edge portion located at an upper edge of the slot. The antenna module is arranged in the metal housing and includes a carrier board, a feeding element, a radiating element with a feeding portion connected to the feeding element, and a first parasitic radiating element arranged on the carrier board and connected or coupled to the first upper edge portion. A vertical projection of the radiating element on the metal housing at least partially overlaps the slot. One side of the first parasitic radiating element is near an edge of the open end. The radiating element is fed with a signal through the feeding element to generate a resonant mode and is coupled to the slot to excite another resonant mode.

摘要： The present invention provides a dual-polarized radiating element comprising a feeding arrangement and four dipole arms. The feeding arrangement comprises four slots, which extend from a periphery towards a center of the feeding arrangement and which are arranged at regular angular intervals forming a first angular arrangement. The four dipole arms extend outwards from the feeding arrangement and are arranged at regular angular intervals to form a second angular arrangement. The second angular arrangement of the four dipole arms is rotated with respect to the first angular arrangement of the four slots.

摘要： A mobile device includes a metal mechanism element, a first radiation element, a second radiation element, and a dielectric substrate. A closed slot is formed in the metal mechanism element. The closed slot has a first edge and a second edge which are opposite to each other. The first radiation element has a feeding point. The second radiation element is coupled to the first edge of the closed slot, and is adjacent to the first radiation element. The second radiation element is at least partially disposed between the first radiation element and the second edge of the closed slot. The first radiation element and the second radiation element are disposed on the dielectric substrate. An antenna structure is formed by the first radiation element, the second radiation element, and the closed slot of the metal mechanism element.

摘要： An antenna device includes a substrate, a first ground layer, a radiation electrode, and waveguide structures. Each of the waveguide structures has a slit and a conductor wall. The slit is positioned in an electric field direction of the radiation electrode and provided in the first ground layer. The conductor wall surrounds the slit and extends in a thickness direction of the substrate. A dimension of the waveguide structure in a magnetic field direction in plan view is greater than ½ of a wavelength of a radio wave emitted by the radiation electrode in a medium of the substrate. A length from the slit to a terminal portion of the waveguide structure is about ¼ of a wavelength of the radio wave emitted by the radiation electrode in the waveguide structure.

摘要： An apparatus is provided that includes a ground plane having a perimeter, at least one support positioned within the perimeter of the ground plane and extending outwardly from the ground plane and at least one multi-port antenna supported by the support at a distance from the ground plane. The multi-port antenna has a different radiation pattern associated with each port. The multi-port antenna operates with a first radiation pattern when a first port is used and operates with a second radiation pattern, different to the first radiation pattern, when a second port, different to the first port, is used. The at least one support defines a slot positioned between the multi-port antenna and the ground plane and/or the ground plane defines a slot.

摘要： A dielectric logging tool for use in a borehole that penetrates a subsurface formation, includes: at least one wall-contacting face with one or more embedded microstrip antennas including a transmit antenna; an oscillator that supplies a transmit signal; a coherent receiver that measures the one or more scattering coefficients; and a processor that derives a formation property from the one or more scattering coefficients. The tool may be conveyed along a borehole, with the scattering coefficients and derived formation property values associated with tool position and orientation to provide a permittivity log.

摘要： An electronic device may be provided with wireless circuitry that includes antenna structures used to determine the position and orientation of the electronic device relative to external wireless equipment. The electronic device may include a housing having a planar conductive layer, a first slot antenna that includes a first bent slot element in the planar conductive layer, and a second slot antenna that includes a second bent slot element in the planar conductive layer. The first and second bent slot elements may be configured to receive radio-frequency signals at the same frequency. The first and second bent slot elements may have the same shape. The electronic device may include control circuitry configured to measure a phase difference between the radio-frequency signals received by the first and second slot antennas. The control circuitry may identify an angle of arrival of the received radio-frequency signals based on the measured phase difference.
