Abstract: A dual polarity antenna including: a first radiator for radiating or for receiving a first radio-frequency (RF) wave having a first linear polarisation, and a second radiator for radiating or for receiving a second RF wave having a second linear polarisation orthogonal to the first linear polarisation. The first radiator includes one or more electrically conductive parts and the second radiator is provided by one or more slots in the one or more electrically conductive parts. An antenna column array may be densified and the size of the array columns may be reduced by locating and/or embedding the second radiator in the first radiator.

Abstract: 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.

Abstract: An outphasing antenna structure is provided that includes a first antenna feeder and a second antenna feeder. A high-PAPR signal is decomposed into a first constant-envelope signal that drives the first antenna feeder and into a second constant-envelope signal that drives the second antenna feeder. The pair of antenna feeders parasitically couple to an antenna that radiates the first and second constant-envelope signals that spatially combine in free space into the high-PAPR signal.

Abstract: Exemplary embodiments are disclosed of antenna assemblies configured for reception of television signals, such as high definition television (HDTV) signals. In an exemplary embodiment, an antenna assembly generally includes a VHF antenna element and a UHF antenna element. The VHF antenna element and the UHF antenna element may be parasitically coupled without a direct ohmic connection between the VHF antenna element and the UHF antenna element. The antenna assembly may be configured to be operable for receiving VHF and UHF high definition television signals without using a diplexer and a VHF balun.
