System and method for modulating a signal at an antenna

摘要: A Direct Spatial Antenna Modulation (DSAM) antenna structure makes use of the instantaneous electromagnetic field state a radiating to achieve direct modulation transmitted signal within antenna. In contrast existing amplitude and phase-only based digital techniques, this innovative technique utilizes an inherent spatial component, mapping data spatially different locations in structure, where each location has transmitting receiving properties. This component can enable, for example, unique increase transmission speed fixed spectral bandwidth with no bit error rate over current phase only techniques. Additionally, DSAM affords important benefits reduced hardware complexity, supply consumption, relaxed amplifier linearity requirements. abstract is not be considered limiting, since other embodiments may deviate from features described Abstract.
