Abstract: Systems and methods of communication synchronization are described herein. An exemplary system includes two or more radios and a cloud controller. The two or more radios are collocated with one another and they communicate with two far radios over a pair of long range wireless links. The two or more radios are configured to transmit and receive in synchronization with one another on a same channel. An off-axis response for each of the two or more radios is reduced compared to their on-axis response for improved signal to noise ratio.

Abstract: A dual reflector earth station antenna (ESA) system for transmitting uplink in a first frequency band and receiving downlink in a second frequency band, the ESA system comprises a reflector; a reflector tracking assembly coupled to the reflector and configured to control the direction of the reflector; a feed horn coupled to the reflector and optimized for a near-constant phase center for both the first frequency band and the second frequency band; a subreflector tracking assembly including a subreflector, configured for tracking in the X, Y and Z-axes and supported proximate a focal point of the reflector; and a control system in communication with the subreflector tracking assembly and comprising at least one processor. The processor is configured to adjust the subreflector of the subreflector tracking assembly along X, Y and Z axes of the reflector until a signal gain of the reflector antenna is maximized for the second frequency band; and wherein a signal gain of the reflector antenna is also simultaneously maximized for the first frequency band due to the optimization of the feed horn for a near-constant phase center for both the first frequency band and the second frequency band.

Abstract: Simultaneous transmission on a shared channel by a plurality of collocated radios is provided herein. The two or more radios are collocated with one another and are communicating with two far radios over a pair of long range wireless links. The two or more radios are configured to transmit and receive in synchronization with one another on a same channel. An off-axis response for each of the two or more radios is reduced compared to their on-axis response for improved signal to noise ratio, and the on-axis response the two or more radios are substantially equal to one another.

Abstract: The present disclosure relates to coaxial dual-band antennas. One example antenna includes a waveguide tube, a ring groove, and a high frequency feed. The waveguide tube has a tubular structure and is configured to transmit a first electromagnetic wave. The ring groove whose opening direction is the same as an output direction of the first electromagnetic wave is on a wall of the waveguide tube. A frequency of the first electromagnetic wave is lower than a frequency of an electromagnetic wave transmitted by the high frequency feed. The high frequency feed is located in the waveguide tube and has a same axis with the waveguide tube.

Abstract: A method for upgrading a dual-band antenna assembly to a tri-band antenna assembly is provided. The dual-band antenna assembly includes a main reflector, and first and second antenna feeds arranged in a coaxial relationship and directed toward the main reflector. The first and second antenna feeds are for first and second frequency bands, respectively. The method includes positioning a third antenna feed through a medial opening in a center of the main reflector, with the third antenna feed directed towards the first and second antenna feeds. The third antenna feed is for a third frequency band. A subreflector is positioned between the main reflector and the first and second antenna feeds. The subreflector includes a frequency selective surface (FSS) material that is reflective for the third frequency band and transmissive for both the first and second frequency bands.

Abstract: Antenna assemblies are described herein. In particular, described herein are multi-focal-point antenna devices and compact radio frequency (RF) antenna devices. Any of these assemblies may include a primary feed that includes a single patterned emitting surface from which multiple different beams of RF signals are emitted corresponding to different antenna input feeds each communicating with the patterned antenna emitting surface. The antenna assembly is therefore capable of emitting beams in the same direction having different polarizations using a single primary feed. Also described herein are compact RF antenna devices having a lightpipe that passes through the single patterned emitting surface.
