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.
