摘要： Devices and methods for detection of active return loss for an antenna element of a plurality of antenna elements of a phased array antenna are provided. An exemplary device can convert a voltage differential at an input of a power amplifier (PA) to first current. The device can convert a coupled voltage corresponding to a signal transmitted from the PA to a respective antenna element, to a second current. The device can convert a reflected voltage corresponding to a signal reflected from the respective antenna element, to a third current. The device can convert the first current, the second current, and the third current to an output voltage at a generator output. The device can further have a controller that can adaptively generate codebooks for transmission based on the output voltage.

摘要： An antenna device includes a main circuit board, a first-type antenna ground-coupled to the main circuit board, and a second-type antenna ground-coupled to the main circuit board. The first-type antenna has a ground structure. The second-type antenna is spaced apart from the first-type antenna and an operating bandwidth of the second-type antenna is greater than an operating bandwidth of the first-type antenna.

摘要： A radio frequency device has a multifunctional tuner that stores measurements of reflection coefficient parameter in a register. The radio frequency device also has a transceiver that has a transmitter. The transceiver may detect a transmitter signal from the transmitter to an antenna in an initial tuning state and then determine whether the transmitter signal is stable. In response to the transmitter signal being stable, the transceiver may measuring the reflection coefficient parameters at the multifunctional tuner. Furthermore, the radio frequency device has a baseband controller that has a memory to store instructions and a processor to execute the instructions. The instructions cause the processor to determine an antenna impedance based on the reflection coefficient parameters, and in response to determining that the antenna impedance is greater than or less than a threshold antenna impedance, iteratively tune the antenna using the multifunctional tuner.

摘要： A structure includes: a base that includes a first surface and a second surface parallel to a first plane, a third surface and a fourth surface parallel to a second plane orthogonal to the first plane, and a fifth surface and a sixth surface parallel to a third plane orthogonal to the first plane and the second plane; a first conductor that expands along the third plane and that extends along a second direction; a second conductor that expands along the fourth plane and that extends along the second direction; a third conductor that expands along the first plane and that is configured to capacitively connect the first conductor and the second conductor; and a fourth conductor that is configured to be electrically connected to the first conductor and the second conductor. The first conductor, the second conductor, and the third conductor are at least partially exposed to exterior space.

摘要： An antenna element includes a dielectric substrate, a radiation electrode, a first ground electrode, a second ground electrode, and a via conductor that connects the first ground electrode and the second ground electrode to each other. The dielectric substrate includes a flat-plate-shaped first part and a second part that is thinner than the first part. The radiation electrode and the first ground electrode are arranged on or in the first part so as to face each other in the thickness direction of the first part. The second ground electrode is spaced apart from the radiation electrode. The second ground electrode is arranged on or in the second part so as to not face the radiation electrode in the thickness direction of the second part. The radiation electrode is capacitively coupled to the second ground electrode and the via conductor.

摘要： A door for a smart shipping container includes a door that has an outside skin strengthened by at least one hollow support beam defining an interior channel thereof. The door also includes embedded computing system disposed within the interior channel of the hollow support beam of the door. The embedded computing system includes a power source, memory, at least one processor, communications circuitry, an antenna and one or more sensors. Optionally, a window is defined in the hollow support beam so as to permit access by the antenna to an exterior of the door. For example, the window can be a three-sided window so as to permit access by the antenna to the exterior of the door irrespective of an opened or closed position of the door.

摘要： A mounting base (14) is fixed to an antenna (13) or an antenna bracket (15) for supporting the antenna (13). A baseband unit (11) and an RF unit (12) are fixed to the mounting base (14). The baseband unit (11) fixed to the mounting base (14) is disposed to face a back part (132) of the antenna (13) and to form a space between the back part (132) and the first enclosure (111). The RF unit (12) fixed to the mounting base (14) is disposed in the space formed between the back part (132) of the antenna (13) and the baseband unit (11) and is coupled to a waveguide flange (132) of the antenna (13). Thus, for example, in a configuration of a point-to-point wireless apparatus in which an RF unit and a baseband unit are separated, restrictions on installation space of the apparatus can be facilitated.
