The crossed-dipole antenna is provided with a core composed of a dielectric material, a reflecting plate, a first element group composed of four first elements that are formed on an outer surface of the core, extend from a central portion of the top surface of the core with a first length L1, and are arranged to be orthogonal to one another, a second element group that resonates at a second resonance frequency f2 and is composed of four second elements that are formed on the outer surface of the core, extend from the central portion of the top surface of the core with a second length L2, and are arranged to be orthogonal to one another, and feeders that transmit electric power to each element. Each of the first elements and the second elements extends along the outer surface of the core and is bent from the top surface to the side surface. The first length L1 of the first elements is less than a fourth of a first wavelength λ1 corresponding to the first resonance frequency f1, and the second length L2 of the second elements is less than a fourth of a second wavelength λ2 corresponding to the second resonance frequency f2.

摘要： Aspects of the embodiments are directed to an on-chip loop antenna and methods of manufacturing the same. In some embodiments, the on-chip loop antenna is in an integrated circuit (IC) die. The IC die comprises metal loops substantially centered around a core region of the IC die in a metallization stack of the IC die, a dielectric between spaces of the metal loops, an electric circuit in the core region electrically connected to the metal loops with an interconnect, and a ground plane in the metallization stack electrically connected to the loops with a first plurality of vias and to the electric circuit with a second plurality of vias. The first plurality of vias is different from the second plurality of vias, and the electric circuit includes an inductor. In some embodiments, the on-chip loop antenna can be carried by a semiconductor package.

摘要： The disclosure concerns an antenna assembly having a substrate with an antenna radiating element and a ground conductor disposed on the substrate, the ground conductor further characterized by a plurality of ground resonators, wherein a length associated with each of the ground resonators increases as the ground resonators are distanced from the antenna radiating element. Additionally, a coaxial cable is routed around the antenna assembly for configuring the coaxial cable as an additional ground resonator associated with the antenna assembly. The resulting antenna provides wide band performance between 700 MHz and 2700 MHz with improved efficiency compared with conventional antennas.

摘要： An antenna and a communications apparatus, where the antenna includes surface radiating patches, inner radiating patches, a first dielectric substrate disposed between the surface radiating patches and the inner radiating patches, and a second dielectric substrate disposed below the inner radiating patches and configured to carry antenna feeders coupled to the inner radiating patches. A dielectric constant or dielectric loss of the first dielectric substrate is lower than that of an organic resin substrate, and a coefficient of thermal expansion of the second dielectric substrate is lower than that of the organic resin substrate.

摘要： An electronic device is provided. The electronic device includes a support member, a front plate disposed on a front surface of the support member, a back plate disposed on a back surface of the support member, a non-conductive structure interposed between the back plate and an edge of the support member and fixed to the support member, and an antenna structure interposed between the back plate and an edge of the support member. At least a portion of the antenna structure may be disposed to face the non-conductive structure. In a region of the non-conductive structure, which faces the antenna structure, a separated distance from the antenna structure varies depending on a distance from a bottom surface of the support member to which the non-conductive structure is fixed.

摘要： Disclosed herein is an antenna device that includes a filter layer, an antenna layer, a divider layer, and ground patterns. The antenna layer has first and second radiation conductors and first and second ground pillars that surround the first and second radiation conductors, respectively. Each of the first and second ground patterns has a first area that overlaps a first space surrounded by the first ground pillars, a second area that overlaps a second space surrounded by the plurality of second ground pillars, and a third area that connects the first and second areas. A width of the third area in a width direction perpendicular to an arrangement direction of the first and second areas is smaller than a width of each of the first and second areas in the width direction.
