A wireless radiation module with multiple miniaturized antennas receiving signals from multiple switchable feed points for enhanced frequency ranges includes a substrate, a radiation portion, and an active circuit. The radiation portion is spaced apart from a radiator. The radiation portion generates multiple radiation modes through coupling with the radiator, and signals are transmitted and/or received from the radiator. The active circuit is electrically connected to the radiation portion for switching between multiple radiation modes of the radiation portion. The wireless radiation module can operate in multiple radiation modes, and cover multiple frequency bands, to increase a bandwidth and have an improved antenna efficiency. The present disclosure also provides an electronic device with the wireless radiation module.

An antenna assembly, a terminal device having the antenna assembly, and a method for improving a radiation performance of an antenna are provided. The terminal device includes an antenna assembly, and a controller. The antenna assembly comprises an antenna, a first adjusting unit, a second adjusting unit, and an antenna switch; the controller is configured to control, based on a current working power of the antenna, the antenna switch to select one of the first adjusting unit and the second adjusting unit to be in an enabled state, so that a radiation direction of the antenna can be adjusted by the selected adjusting unit to a radiation direction formed based on the selected adjusting unit.

The disclosed structures and methods are directed to antenna systems configured to transmit and receive a wireless signal in and from different directions. A switchable lens antenna has excitation ports radiating radio-frequency (RF) wave into a parallel-plate waveguide structure, and a frequency selective structure (FSS). The antenna presented herein is configured to operate in two modes depending on an initial steering angle of the RF wave propagating in the parallel-plate waveguide structure. When the initial steering angle is about or less than a threshold steering angle, FSS is OFF due to its stubs being electrically disconnected from the parallel-plate waveguide structure. When the initial steering angle is higher than the threshold, FSS is ON with stubs being electrically connected to the parallel-plate waveguide structure. When ON, FSS provides phase variance to the RF wave propagating in the parallel-plate waveguide structure and increases steering angle of the RF wave.

Methods and apparatuses for performing optical inspection of varactor diodes in an antenna are disclosed. In some embodiments, the method of testing an antenna having varactor diodes comprises: selecting a plurality of varactor diodes to be placed in a light emitting state; forward biasing the selected varactor diodes to a magnitude at which the selected varactor diodes are to emit light; and detecting one or more faulty varactor diodes of the selected varactor diodes based on their emitted light intensity.

One embodiment provides an electronic device comprising an antenna. The electronic device comprises: an array antenna including a plurality of antenna elements; a transceiver circuit operatively coupled to the array antenna and configured to control a signal of a millimeter wave band applied to the array antenna; and a processor operatively coupled to the transceiver circuit and configured to control the transceiver circuit. The processor can emit a signal to a second electronic device through one antenna element of the plurality of antenna elements, select an optimum antenna element on the basis of a data rate in the second electronic device which has received the signal, and communicate with the second electronic device through the selected antenna element.

The present disclosure provides an antenna module including a substrate, a first antenna disposed on the substrate and a second antenna disposed on the substrate and spaced apart from the first antenna. The first antenna is configured to have a first operating frequency and the second antenna is configured to have a second operating frequency different from the first operating frequency. The antenna module further includes an element configured to focus an electromagnetic wave transmitted or received by the first antenna and the second antenna. A semiconductor device package is also disclosed.

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.

A universal transmit-receive (UTR) module for phased array systems comprises an antenna element shared for both transmitting and receiving; a transmit path that includes a transmit-path phase shifter, a driver, a switch-mode power amplifier (SMPA) that is configured to be driven by the driver, and a dynamic power supply (DPS) that generates and supplies a DPS voltage to the power supply port of the SMPA; and a receive path that includes a TX/RX switch that determines whether the receive path is electrically connected to or electrically isolated from the antenna element, a bandpass filter (BPF) that aligns with the intended receive frequency and serves to suppress reflected transmit signals and reverse signals, an adjustable-gain low-noise amplifier (LNA), and a receive-path phase shifter. The UTR module is specially designed for operation in phased array systems. The versatility and wideband agility of the UTR module allows a single phased array system to be designed that can be used for multiple purposes, such as, for example, both radar and communications applications.

A power transmitting method of a wireless communication system includes a metasurface. The method includes transmitting power of a power supply device to a target device through the metasurface comprising N cells, where N is an integer; estimating, by the metasurface, a channel between the metasurface and the target device based on the power received by the target device and a property matrix with a magnitude of (N+1)×(N+1); adjusting, by the metasurface, a phase of each cell of the N cells based on the estimated channel; and reflecting, by the metasurface, the power transmitted from the power supply device to the target device using the adjusted phase of each cell of the N cells. The property matrix includes information indicating whether each cell of the N cells is turned on and information about a bias value of the wireless communication system.
