Abstract: An example semiconductor package comprises a patch antenna formed in a first conductor layer of a multilayer package substrate. The multilayer package substrate comprises conductor layers spaced from one another by dielectric material and coupled to one another by conductive vertical connection layers. The multilayer package substrate has a board side surface opposite a device side surface. The semiconductor package further comprises a semiconductor die mounted to the device side surface of the multilayer package substrate spaced from and coupled to the patch antenna. An antenna horn is mounted to the device side surface and aligned with the patch antenna using a mounting structure. The semiconductor package further comprises a reflector formed on a second conductor layer in the multilayer package substrate. The second conductor layer is positioned closer to the board side surface of the multilayer package substrate compared to the patch antenna.

Abstract: A pointing device for detecting motion relative to a surface includes a transmitter configured to emit an electromagnetic signal toward the surface. The pointing device further includes a receiver configured to receive a reflection of the electromagnetic signal from the surface. The pointing device further includes a processor configured to determine the motion based on a Doppler-shift between the electromagnetic signal and its reflection.

Abstract: This document describes apparatuses, methods, and systems for a hybrid horn waveguide antenna. The hybrid horn waveguide antenna includes a waveguide, described in two sections, and an antenna section having both flaring features and step features. The first waveguide section is electrically coupled to a transmitter/receiver (e.g., transceiver) and defines an energy path along an x-axis. The second waveguide section transitions the energy path to travel along a z-axis. The antenna section has a first aperture that is coupled to the second waveguide section and includes flaring wall features in one plane (e.g., the E-plane) and step features in a second plane (e.g., the H-plane). The waveguide may further include an iris between the first waveguide section and the second waveguide section. Further, the hybrid horn waveguide antenna section may be formed from an upper structure and a lower structure manufactured via injection molding and then mated.

Abstract: A dual port, slot-based multiple-input-multiple-output (MIMO) antenna is described. The antenna includes a dielectric circuit board, a metallic layer, four tapered feed horns and adjustable voltage sources. A first pentagonal loop slot line and a second pentagonal loop slot line are etched into the metallic layer. The tapered feed horns are located on an opposite side of the dielectric circuit board and are connected to input signal sources. Adjustable voltage sources are connected to varactor diodes of the first and seconds pentagonal loop slot line. The antenna resonates with circular polarization at resonant frequency in an ultra-high frequency sub-GHz range of about 578 MHz to about 929 MHz when an input signal is applied to each feedline. A dual port, slot-based single element antenna is also described.

Abstract: The advent of fifth generation technology systems leads to seamless connectivity requirements for loT-based applications. High frequencies of operation lead to inherent problem of path loss, and to mitigate designing of passive reflecting intelligent surfaces for practical operations are challenging. This disclosure relates a method to enable sectoral area coverage under network applications by topologically modulated reflecting intelligent surfaces. A Minkowski-shaped fractal unit cell is received as an input. The Minkowski-shaped fractal unit cell is characterized to obtain unit cell dimension with independent reflection-phase characteristics. The independent reflection-phase characteristics are utilized to identify distinct unit cell elements. Surface layouts are generated by the distinct unit cell elements. The surface layouts are characterized with respect to an incoming source radiation pattern to identify reflected radiation pattern parameters. The real-time sectoral signal coverage is designed based on the reflected radiation pattern parameters of the surface layouts and position of Ku-band horn antennas.
