Abstract: A lighting device (such as a LED bulb) has a light source (18), a base part (12) and an upper part (62) mounted over the base part (12) with an internal volume (64) defined between them. Within the internal volume (64) there is a two-segment antenna. A first antenna segment (40) extends outwardly from the base part (12) towards the internal volume (64) and a second antenna segment (50) is held by the upper part (62) and mounted partially over the first antenna segment (40). The first and second antenna segments (40, 50) are physically separated but electrically coupled.

Abstract: A detector for detecting terahertz electromagnetic radiation comprises a substrate and a pair of electrically isolated detector elements supported thereon. Each detector element comprises a pair of antenna elements having a gap therebetween and a switch element comprising one or more pieces of photoconductive semiconductor material connected between the antenna elements across the gap. The pairs of antenna elements of the respective detector elements are configured so that, when the switch element is conductive, current is generated between the antenna elements by polarisation components of incident terahertz electromagnetic radiation having polarisation directions in respective sensing directions that are perpendicular, thereby providing simultaneous detection of perpendicular polarisation components of incident terahertz electromagnetic radiation.

Abstract: An ACT film has a plurality of rectenna, each having having an antenna and a diode. The ACT film is manufactured using nanoimprint lithography and roll-to- roll processes. An imprint template is overlaid on a feedstock that has two metal layers separated by one or more oxide layers. The feedstock is etched to expose the lower metal layer. The lower metal layer is undercut to create a discontinuity in the lower metal layer to avoid a short to the diode in the rectenna. A metamaterial film is also made. To complete manufacture of the ACT film, the rectenna film and the metamaterial film are aligned to ensure the rectennas in the rectenna film are located over the holes in the metamaterials in the metamaterial film. Once aligned, the rectenna film and the metamaterial films are bonded together.

The first slot is an open-ended slot and is coupled to a first antenna member to form a first slot antenna. The first slot antenna operates in a first predetermined range of frequencies. The second slot is a close-ended slot and is separated from the first slot by the separating member.

Abstract: Systems, methods, and devices relating to an antenna element and to an antenna array. A three level antenna element provides wideband coverage as well as dual polarization. Each of the three levels is a substrate with a conductive patch with the bottom level being spaced apart from the ground plane. Each of the three levels is spaced apart from the other levels with the spacings being non-uniform. The antenna element may be slot coupled by way of a cross slot in the ground plane. The antenna element, when used in an antenna array, may be surrounded by a metallic fence to heighten isolation from other antenna elements.

Abstract: A metal chassis for a mobile device that is configured to transmit a signal of a wavelength. A first side of the chassis faces the inside of the mobile device and includes a first aperture that has a dimension that comprises a first subwavelength width of a slot in the chassis. A second side of the chassis faces free space and includes a second aperture that has a dimension that comprises a second subwavelength width of the slot in the chassis. A channel connects the first aperture and the second aperture. The slot has a length dimension and the channel may be centered along the length dimension. The channel is configured to support a transverse electromagnetic mode for propagation of the signal from the first aperture through the channel to the second aperture. As a part of a mobile device the chassis acts as a secondary radiator for the mobile device.
