An electronic device may have an antenna that conveys radio-frequency signals at frequencies greater than 10 GHz. The antenna may be embedded in a substrate. The substrate may have routing layers, first antenna layers on the routing layers, second antenna layers on the first antenna layers, and a third antenna layers on the second antenna layers. The antenna may include first traces on the first antenna layers, second traces on the second antenna layers, and third traces on the third antenna layers. The first antenna layers may have a first bulk dielectric permittivity. The second layers may have a second bulk dielectric permittivity. The third layers may have a third bulk dielectric permittivity. At least one of the first, second, and third bulk dielectric permittivities may be different from the others. This may differentially load the antenna across the antenna layers, thereby broadening the bandwidth of the antenna.

An electronic device may include a phased antenna array. The array may include co-located first and second antennas formed on a dielectric substrate. The first antenna may include a first patch element and multi-layer parasitic structures. The multi-layer parasitic structures may include a first set of co-planar parasitic elements. The first set of parasitic elements may overlap the first patch element and may be separated by a gap. The multi-layer parasitic structures may include an additional parasitic element that overlaps the gap. The second antenna may include a second patch element that is co-planar with the additional parasitic patch. The second patch element may at least partially overlap one of the parasitic elements in the first set. The first and second patch antennas may collectively cover first and second frequency bands while occupying a minimal amount of space on the dielectric substrate. 1. An electronic device comprising:a dielectric substrate having first, second, and third layers, the second layer being interposed between the first and third layers;a first patch element on the first layer, the first patch element being configured to radiate in a first frequency band greater than 10 GHz;a first positive antenna feed terminal coupled to the first patch element;first and second parasitic patches on the second layer, the first and second parasitic patches at least partially overlapping the first patch element and being separated by a gap that overlaps the first patch element;a third parasitic patch on the third layer, the third parasitic patch overlapping the gap and the first patch element;a second patch element on the third layer, the second patch element at least partially overlapping the first parasitic patch and being configured to radiate in a second frequency band at frequencies greater than the first frequency band; anda second positive antenna feed terminal coupled to the second patch element.2. The electronic device of claim 1 , further ...

Electronic Devices Having Multiple Phased Antenna Arrays

An electronic device may include first and second phased antenna arrays that convey radio-frequency signals at frequencies greater than 10 GHz. The second array may have fewer antennas than the first array. Control circuitry may control the first and second arrays in a diversity mode and in a simultaneous array mode. In the diversity mode, the first array may form a first signal beam while the second array is inactive. When the first array is blocked by an object or otherwise exhibits unsatisfactory performance, the second array may form a second signal beam while the first array is inactive. In the simultaneous mode, the first and second arrays may form a combined array that produces a third signal beam. The combined array may maximize gain. Hierarchical beam searching operations may be performed. The arrays may be distributed across one or more modules.

Radio-frequency modules having high-permittivity antenna layers

Номер: US11923621B2
Автор: Jiangfeng Wu, Lijun Zhang, Simon G. Begashaw, Siwen Yong, Yi Jiang

An electronic device may be provided with a phased antenna array on an antenna module. The array may include low band antennas and high band antennas that radiate at frequencies greater than 10 GHz. The module may include antenna layers, transmission line layers, and ground traces that separate the antenna layers from the transmission line layers. The low band antennas and the high band antennas may have radiators patterned onto the antenna layers. The radiators may be fed by transmission lines on the transmission line layers. The antenna layers may have a dielectric permittivity that is greater than the dielectric permittivity of the transmission line layers. This may serve to reduce the lateral footprint of the low band and high band antennas, which allows the antennas to be interleaved along a common linear axis in the phased antenna array, thereby minimizing the lateral footprint of the antenna module.

A head-mounted device may have a head-mounted housing that is configured to be worn on a head of a user. While the head-mounted device is being worn, left and right displays in optical modules in the head-mounted device may provide images to eye boxes located rearward of the head-mounted device. A forward-facing publicly viewable display on a front portion of the head-mounted device may be covered with a transparent housing portion forming a display cover layer. Millimeter wave antennas may be mounted under a dielectric member that is interposed between the antennas and an edge portion of the transparent housing portion. The antennas may have planar outer surfaces. The dielectric member may have a planar surface separated from the planar outer surfaces by air gaps and a curved outer surface.
