AI Technical Summary

Benefits of technology

This patented technology uses a special type of signal called quadrature amplitude modulation (QAM) that allows signals transmitted through antennas at different angles to have equal amplitudes but opposite phases. By adjusting these waves' time delays based on their needs, it can improve the precision and reliability of radio wave transmission over long distances or even across space. It also makes use of advanced materials like ceramics instead of traditional metals used in previous designs due to its higher energy storage capabilities compared to other types of devices.

Problems solved by technology

Technological Problem: Current phase shaping techniques for electronic waveforms use Gallium Arsenic High Electron Mobility Transistors (GAN), but they require expensive materials like GA's and SiC due to their low heat resistance and small size. Additionally, current methods result in less precise phase changes compared to other technologies that could improve certain aspects of these types of technology.
