Efficient Satellite Downlink with a Ka Band Dual Circular Polarization Transmitter
A new low-loss transmitter allows higher precision low-orbit satellite earth monitoring, according to a study by Tokyo Tech researchers. The novel transmitter works in the Ka band of the microwave frequency spectrum, where no efficient transmission has been possible so far. By using circularly polarized signal, and an innovative internal calibration scheme, efficient transmission with low signal noise and wide-angle scanning is demonstrated.
