摘要： Methods and systems are described for providing end-to-end beamforming. For example, an end-to-end beamforming system include a relay satellite and a ground network to provide communications to user terminals located in user beam coverage areas. The ground network includes geographically distributed access nodes and a central processing system (CPS). Beamformers of the ground network generate forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the satellite, produce forward downlink signals that combine to form forward user beams.

摘要： Disclosed is a multifunctional GNSS antenna belonging to the technical field of communication technology, comprising: a PCB, a first dielectric plate, and a first radiating component arranged in sequence, wherein the PCB is connected with the first radiating component by a first feeding component, a second radiating component and a plurality of metalized vias are arranged on the first dielectric plate, the second radiating component is connected with the PCB by a second feeding component, the plurality of metalized vias are arranged around the first radiating component, and the second radiating component is arranged on an outer side of the plurality of metalized vias. The metalized vias increase the capacitive coupling and form the protection for the first radiating component located therein, which reduces the signal interference and coupling of the third radiating component to the first radiating component effectively, which is conducive to implementation miniaturization of the antenna.

摘要： Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.

摘要： A non-invasive analyte sensor includes a receive side with a superheterodyne circuit. The superheterodyne circuit include a mixer with an input that is electrically connected to a receive antenna, and a radio frequency generator connected to another input of the mixer and that is configured to generate a radio frequency signal. The mixer outputs a signal that is based on a frequency of a signal received by the receive antenna and the frequency of the signal generated by the radio frequency generator.

摘要： In a GNSS signal receiving antenna, a radiation pattern of an antenna unit of the antenna includes four sub-patterns that form a rectangular shape and each of the sub-patterns comprises a first part, a second part and a third part communicated with each other. The first part is communicated with the second part and the second part is communicated with the third part. The four sub-portions form a rectangular shape with an end portion of the third part of each sub-pattern disposed opposite to a side portion of the first part of a next adjacent sub-pattern. The four sub-patterns are not communicated with each other. The GNSS signal receiving antenna can receive both a traditional right-handed circularly polarized signal and a left-handed circularly polarized signal. Multiple antenna units may form an array antenna for directional GNSS signal reception.

摘要： A high frequency module includes a duplexer that includes a transmission filter, a receive-only filter, and a power amplifier that power-amplifies a transmission signal. In order to improve the isolation characteristics between a transmission signal and a reception signal at the duplexer, the receive-only filter is arranged between the power amplifier and the duplexer.
