We have previously considered the use of a modified, conical, folded helix antennas as the energy storage and radiation mechanism for an electrically-small, high power microwave (HPM) system. Our previous results allowed us to integrate the antenna with a HPM switch to achieve a resonance of below 40 MHz for an overall antenna dimension of 101.3 cm (ka = 0.42). In this paper, we consider other folded helix geometries in order to analyze the best one for compact, low-frequency HPM applications. The antennas were modeled using CST Microwave Studio, and each antenna type was evaluated for its resonant frequency, local field enhancement, and radiation properties.
