Abstract: An electronic device may be provided with an antenna module having a substrate. A phased antenna array of dielectric resonator antennas and a radio-frequency integrated circuit for the array may be mounted to one or more surfaces of the substrate. The dielectric resonator antennas may include dielectric columns excited by feed probes. The feed probes may be printed onto sidewalls of the dielectric columns or may be pressed against the sidewalls by biasing structures. A plastic substrate may be molded over each dielectric column and each of the feed probes in the array. The feed probes may cover multiple polarizations. The array may include elements for covering multiple frequency bands. The dielectric columns may be aligned a longitudinal axis and may be rotated at a non-zero and non-perpendicular angle with respect to the longitudinal axis.

Abstract: 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.

Abstract: This invention relates generally to a novel serine/threonine protein kinase, specifically to hormonally up-regulated, neu-tumor-associated kinase (HUNK); and to the role of HUNK in tumor metastasis, primary tumor development, and the prediction of tumor behavior.
