Abstract: Systems, apparatuses, and methods provides for technology that controls a confocal antenna system. The technology controls an Integrated Phased Array (IPA) feed system to emit electromagnetic energy towards a sub-reflector, where the sub-reflector reflects the electromagnetic energy to a main reflector, and further where the main reflector receives and reflects the electromagnetic energy to form a radiation pattern on an area. The radiation pattern has a first size and a first gain. The technology conducts an identification that the radiation pattern is to be adjusted so as to adjust the first size to a second size and adjust the first gain to a second gain. In response to the identification, the technology moves the main reflector linearly along a first axis, and electronically steers a beam of the electromagnetic energy emitted from the IPA feed system towards the sub-reflector.

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: A multiple-feed antenna system includes a first feed configured to communicate signals in a first frequency range of a plurality of frequency ranges and a second feed configured to communicate signals in a second frequency range of the plurality of frequency ranges. A subreflector assembly is configured to move among multiple positions that include a first position and a second position. When the subreflector assembly is in the first position, a first element of the subreflector assembly redirects a signal reflected by a primary reflector to the first feed. When the subreflector assembly is in the second position, a second element of the subreflector assembly redirects the signal reflected by the primary reflector to the second feed.

Abstract: Apparatus for dual-band antenna and communications tower comprising such apparatus are provided. The apparatus comprises a first part (202) comprising first and second propagation paths configured to selectively propagate signals of a first frequency with either a first polarization state or a second polarization state, a transition part (204) rotatable between first and second transition positions to selectively propagate signals of a second frequency along the second signal path with the first polarisation state when in the first transition position and with the second polarisation state when in the second transition position and a rotator part rotatable between first and second rotator positions. Wherein, the rotator part is configured to orientate the polarisation of signals in the second signal path in order to couple the second signal path to an interface, and allow propagation of signals in the first signal path in either the first or second rotator positions.

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.
