Radiation-enhanced dual-inverted bowlers antenna for high-power mesoband system.

We propose a novel radiation-enhanced dual-inverted bowlers antenna to pursue a maximal radiated electric field (E-field). Based on increasing the stored energy and the high-frequency component of the excitation pulse, the new structure significantly improves the radiation performance without increasing the generator output voltage or antenna size. Computer simulations show that the radiated E-field increases by a factor of 2.7 relative to the same sized conventional biconical antenna. Under a charge voltage of 300 kV, the experimental far-field voltage is 110 kV (22 kV/m at 5 m) and the voltage gain is 0.37. This voltage gain is an improvement of at least 23% over typical biconical antennas. This work brings new opportunities to improve the radiation performance of high-power mesoband systems.
