ABSTRACT This letter presents a compact integrated self‐resonating microwave source capable of simultaneous dual‐band operation and polarisation reconfiguration. The design integrates a modified dual‐polarised patch antenna with a reconfigurable pulse‐triggered network. This reconfigurable pulse‐triggered network charges the antenna to a high DC potential and then triggers the accumulated charges to oscillate, therefore directly converting DC energy into concurrent dual‐band RF pulses. Moreover, the reconfigurable nature of the pulse‐triggered network enables dynamic switching between two orthogonal linear polarisation states (e.g., 0° and 90°). Both simulations and experiments validate the microwave source's capability to generate concurrent dual‐band pulses while dynamically reconfiguring its polarisation state.
