Abstract
Electrically small antennas (ESAs) operate with low radiation efficiency and high Q-factor, requiring greater power consumption and slower data rates in wireless communication systems. Direct Antenna Modulation (DAM) refers to a class of modulation techniques, often utilizing a time-varying switch, which significantly reduces the symbol transition time in wireless communication systems with ESAs. Despite the ability to avoid the band-limited nature of ESAs, the increased data rates associated with DAM come at the expense of undesired radiation transients and power radiated in sidebands, which can be disruptive to other communication channels. These effects vary greatly with antenna geometry. In this project, we study these by using a full-wave solver and analyzing DAM circuit simulation results.
