Compact EZ antenna arrays for field management in HPM applications

Previously, we demonstrated the integration of an electrically small EZ antenna with a mesoband high power microwave (HPM) quarter-wave oscillator source. This design was confirmed with both computer modeling and experimental results for an EZ antenna with ka = 0.47. We also have reported results from computer simulations of a dual-band HPM EZ antenna system with resonances near 500 MHz and 1.5 GHz. In this paper we discuss the design of an EZ antenna array fed via the same mesoband source through a radial waveguide designed for handling high power levels.
