摘要： An adaptable microwave radio transceiver system having a microwave radio transceiver and at least two waveguide adapters, where the microwave radio transceiver is adapted for at least two waveguide frequency bands and includes at least one radio port that includes a corresponding probe of a fixed length and extends via an inner insulating part in a bottom in the corresponding radio port. Each waveguide adapter comprises has a first end facing the corresponding bottom where each first end includes a bottom wall with an outer insulating part through which the corresponding probe is adapted to protrude a protrusion distance. The protrusion distance is dependent on a thickness of the bottom wall, where at least two waveguide adapters have different thickness of the corresponding bottom wall, where any one of the waveguide adapters is exchangeably mountable to the radio port.

摘要： Example embodiments relate to low elevation side lobe antennas with fan-shaped beams. An example radar unit may include a radiating plate having a first side and a second side with an illuminator, a waveguide horn, a waveguide opening, and a radiating sleeve extending into the first side of the radiating plate. The waveguide opening is positioned on the first end of the first side and the radiating sleeve is positioned on the second end of the first side. The radar unit also includes a metallic cover coupled to the first side of the radiating plate such that the metallic cover and the radiating plate form waveguide structures. The waveguide horn is configured to receive, from an external source, electromagnetic energy provided through the waveguide opening via a first waveguide and provide a portion of the electromagnetic energy to the illuminator via a second waveguide such that the portion of the electromagnetic energy radiates off the illuminator and through the radiating sleeve into an environment of the radar unit as one or more radar signals.

摘要： An active passive antenna arrangement as made up of an array of 5G antennas interleaved with multiband antenna structures that may be low band (LB) passive antennas. The 5G antenna array may be a mMIMO active array. The LB antennas are formed using conductive elements on thin supporting sheets that fit within the space between the 5G antennas. The substrates, and hence the radiating elements of the LB antennas, may be arranged so as to generally appear to form four sides of a rectangular box with the top and bottom surfaces removed. Thus, the LB antennas may be thought of as having been “slipped in” amongst a preexisting array of 5G antennas. Each LB antenna may surround one or more of the 5G antennas and 5G antennas of the array may also be external to an LB antenna.

摘要： Provided is a scan driving circuit including a plurality of unit scan driving circuits, at least one of the plurality of unit scan driving circuits including: a first transistor configured to receive a prior scan signal in synchronization with a first clock signal and to respond to an enable level of the prior scan signal to output a second clock signal as a corresponding scan signal during one cycle of the first clock signal; a second transistor coupled between the first transistor and a first voltage; and a third transistor coupled to a gate of the second transistor and configured to be turned on by a first signal. A width of a first wire configured to transfer the first clock signal and a width of a second wire configured to transfer the second clock signal are larger than that of a third wire configured to transfer the first signal.

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： Microwave antenna systems include a parabolic reflector antenna having a feed bore and a feed assembly. The feed assembly includes a coaxial waveguide structure that extends through the feed bore, a sub-reflector, and a first dielectric block that is positioned between the coaxial waveguide structure and the sub-reflector. The coaxial waveguide structure includes a central waveguide and an outer waveguide that circumferentially surrounds the central waveguide. One of the central waveguide and the outer waveguide extends further from the feed bore towards the sub-reflector than the other of the central waveguide and the outer waveguide.

摘要： A ring focus antenna system has an ultra-wide bandwidth for receiving and transmitting electromagnetic (EM) signals. The system includes a main reflector having an axis of rotation and a splash plate feed assembly consisting of a waveguide and a sub-reflector which is substantially aligned with the axis of rotation. The sub-reflector has surfaces that include segments of a displaced ellipse, having a first focal point which coincides with an ISO phase center located inside the waveguide and a second focal point located on a ring focus of the main reflector. A dielectric support for the sub-reflector has a shaped boundary which eliminates refraction at the dielectric-air interface. In one embodiment, the ultra-wide bandwidth includes EM frequencies belonging to Ku-band and Ka-band communication frequencies. The waveguide may be configured as a quad-ridged polarizing waveguide.
