| 12412989 | 9/9/2025 | KING FAHD UNIVERSITY OF PETROLEUM MINERALS | Dhahran, | Ultra high frequency antenna with variable frequency range | A dual feed slot-based circularly polarized wideband ultra high frequency (UHF) antenna for a cubic shaped satellite (Cube-Sat) is described. The UHF antenna includes a circuit board, a metallic layer, a hexagonal meandered slot, a capacitor, a first feed horn, and a second feed horn. The circuit board has a front side and a back side separated by a dielectric material. The metallic layer covers the back side of the circuit board. The hexagonal meandered slot symmetrically includes six legs of equal length and six vertexes. The capacitor is switchably connected to the metallic layer. The first... |
| 12413286 | 9/9/2025 | Viasat | San Diego-Carlsbad-San Marcos, CA | Beam management using sparse antenna arrays | Methods, systems, and devices communications are described. A terminal may be identified with a geographic region. First beam coefficients may be determined for an antenna array having interelement spacing of antennas that is different across the antenna array. The first beam coefficients may be used to form a first beam for the terminal, where a coverage area of the first beam may encompass the geographic region. The first beam may be used to communicate with the terminal. Based on a utilization of the first beam exceeding a threshold, second beam coefficients may be determined for the antenn... |
| 12413458 | 9/9/2025 | Hughes Network Systems | Washington-Arlington-Alexandria, DC-VA-MD-WV | Frequency modulation in a communications network | A processor can be configured to execute instructions stored in the memory to position a first point in a grid space that represents an unmodulated signal component of a first signal based on a characteristic of a frequency modulator generating the first signal. The frequency modulator can include a first input to receive data from a baseband source and can include a second input to receive a second signal from a local oscillator. The processor can determine, in the grid space, a first angle between a first line segment from a reference point to the first point and a second line segment from t... |
| 12413560 | 9/9/2025 | The Boeing | Washington-Arlington-Alexandria, DC-VA-MD-WV | Virtual transponder utilizing inband commanding | Systems, methods, and apparatus for a virtual transponder utilizing inband commanding are disclosed. In one or more embodiments, a disclosed method comprises receiving, by a payload antenna on a vehicle via a hosted receiving antenna, encrypted hosted commands transmitted from a hosted payload (HoP) operation center (HOC). The method further comprises receiving, by the vehicle, encrypted host commands transmitted from a host spacecraft operations center (SOC). Also, the method comprises reconfiguring a payload on the vehicle according to the unencrypted host commands and/or the unencrypted hos... |
| 12414107 | 9/9/2025 | VIASAT | San Diego-Carlsbad-San Marcos, CA | Improving network transmit power profile by randomizing resource grants on a multi-user communications network | Schedulers that allocate resource grants on a slot-by-slot basis within a scheduling epoch or frame can create a front-loading effect where allocations occur more frequently in slots earlier in frames. To address these and other issues, systems and methods are disclosed for scheduling resource grants in a network to improve network transmit power profiles. For example, a scheduler is configured to randomize the order of slots in a scheduling epoch or frame, with different randomizations for different schedulers, to more evenly distribute slots with resource grant allocations to prevent or redu... |
