Design and Simulation of Ultra-Wideband Combined Antenna for High-Power Microwave
An ultra-wideband (UWB) combined antenna for high-power microwave (HPM) application is designed in this paper. Tapered-slot balun is adopted to enhance the power capacity. In order to realize the smooth impedance variation from the feeder to the free space and improve the radiation efficiency and percentage bandwidth (PBW), principles of exponential taper, triangular taper and Klopfenstein taper are analyzed. The results of combined antennas with three types of impedance tapered structures are compared. Also, the size of magnetic dipole is optimized by adjustable plate to improve the low-frequency performance. Finally, a high-power ultra-wideband (HP-UWB) combined antenna with length of 300 mm is designed and simulated. With excitation of the high-power bipolar pulse whose amplitude is 125 kV, width is 2.7 ns and center frequency is 268 MHz, the weighted radiation efficiency of the antenna is 82.6%, while PBW is 146.9%. The power capacity of the antenna can reach to 200 MW.
