Previously we reported on the integration of an electrically small EZ antenna with a mesoband HPM source based on a coaxial, quarter-wave oscillator. In our previous work, we demonstrated through modeling and experiment the use of an antenna with ka = 0:47 for radiation of HPM signals. In the present paper, we present a design that allows the oscillator to function as a dual-frequency source by including multiple trigger points. We further adapt the EZ-antenna to be dually resonant with no increase in size through the use of orthogonal polarization coupling.
