DC-Assisted Stabilization of Internal Oscillations for Improved Symbol Transitions in a Direct Antenna Modulation Transmitter
Huang, D., Schab, K., Dusenbury, J. K., Sluss, B., & Adams, J. J. (2021, August 13). IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES, Vol. 8.
author keywords: Dams; Antennas; Oscillators; Switches; Transmitting antennas; Integrated circuit modeling; Antenna measurements; Direct antenna modulation (DAM); electrically small antennas (ESAs); parasitic circuit model; time-varying circuits
TL;DR:
Measured phase shift keyed waveforms transmitted using the modified direct antenna modulation system with an auxiliary DC source show significant increases in signal fidelity, including a 10–20-dB reduction in error vector magnitude compared to a time-invariant system.

Investigation of Ringing Effects on Phase Shift Keyed Direct Antenna Modulation Transmitters
2020 IEEE INTERNATIONAL SYMPOSIUM ON ANTENNAS AND PROPAGATION AND NORTH AMERICAN RADIO SCIENCE MEETING, pp. 1817–1818.
TL;DR:
It is demonstrated that it is the parasitics of the circuit that reduce the ability of the system to store voltage and achieve fast transitions, particularly between certain combinations of symbols.

Minimization of Antenna Quality Factor
IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, 65(8), 4115–4123.
author keywords: Antenna theory; eigenvalues and eigenfunctions; electromagnetic theory; optimization methods; Q-factor
TL;DR:
It is shown that the dual problem can easily be solved and always results in minimal quality factor, and the class of solvable problems is significantly extended.
