An integrated polarization-reconfigurable pulse transmitter based on a reconfigurable pulse-triggered network

Abstract This work proposes an integrated pulse transmitter with polarization reconfigurability. A reconfigurable pulse-triggered network is designed and seamlessly integrated with a dual-polarized radiator within the compact transmitter structure. This integration allows the radiator to sequentially perform DC charge accumulation, pulse oscillation, and radiation during each pulse cycle. Moreover, the reconfigurable pulse-triggered network introduces two operating modes, enabling the pulse transmitter to switch between different polarization states. Experiments demonstrate that the proposed pulse transmitter can directly convert DC energy into radiated pulses with switchable polarization modes. The pulse signal with a peak-to-peak voltage of 1.6 V is received in the −45° polarization direction at 1.5 m under mode 1, and switches to +45° polarization with a peak-to-peak voltage of 1.6 V under mode 2.
