An antenna module (100) includes a dielectric substrate (130) having a multilayer structure, a first radiating electrode (121) and a ground electrode (GND) that are disposed in the dielectric substrate (130), and a second radiating electrode (150) disposed in a layer between the first radiating electrode (121) and the ground electrode (GND). The first radiating electrode (121) is a power feed element to which radio frequency power is supplied. When the antenna module (100) is viewed in plan from a normal direction of the dielectric substrate (130), the first radiating electrode (121) and the second radiating electrode (150) at least partially overlap with each other. A thickness of the second radiating electrode (150) is larger than that of the first radiating electrode (121).

A measuring instrument having an antenna element coupled to the measuring instrument is disclosed. The measuring instrument includes a planar substrate with an antenna connector coupled to the planar substrate and further coupled to the antenna element. At least a portion of the planar instrument comprises indicia wherein said indicia collectively forms the measuring instrument.

An antenna includes a waveguide defined by a gap between a backplane with radial support ribs and a facesheet, a teardrop-shaped feed pin at a center of the backplane, and a foam spacer between the backplane and facesheet. An outward facing side of the facesheet includes thermal paint. The facesheet includes pairs of through-hole slots for releasing portions of a wave of radiation in the waveguide to generate a transmit-beam or to receive the receive-beam to generate the wave of radiation. The pairs may be disposed as a spiral array about a center of the facesheet. Each of the pairs may include first and second slots. A length of the second slot is oriented approximately perpendicular to a length of the first slot. Dispositions of the slots are set by a computer process. The dispositions optimize a trade-off between transmit and receive gains.

An antenna stack structure according to an embodiment includes a protective layer, and an antenna electrode layer formed directly on a surface of the protective layer. The antenna electrode layer includes a first electrode layer and a second electrode layer having a lower reflectance than that of the first electrode layer. A visual recognition of electrode are prevented by the second electrode layer.

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.

An antenna arrangement for an aircraftincludes an antenna unit, a radome structure covering the antenna unit, and a mounting device for mounting the antenna arrangement to an outer surface of an aircraft component. The antenna unit is mounted to or integrally formed with the radome structure and the radome structure is mounted to or integrally formed with the mounting device.

Front-shielded, coplanar waveguide, direct-fed, cavity-backed slot antennas are described. Various implementations form an antenna unit capable of millimeter waveform and/or microwave waveform transmissions. A bottom shielding structure of the antenna unit defines a cavity, where various implementations include one or more dampening structures within the cavity. Some implementations includes a slot antenna within the cavity defined by the bottom shielding structure, such as a coplanar waveguide (CPW) direct-fed slot antenna, to form a cavity-backed slot antenna. Some implementations connect a top shielding structure to the bottom shielding structure to encase the slot antenna. In one or more implementations, the top shielding structure includes aperture windows to allow waveforms within a frequency range from about between 600 Megahertz (MHz) to 72 Gigahertz (GHz). and radiated by the slot antenna to radiate outward from the antenna unit.
