A Ultra-Wideband Combined-Oscillator Antenna Design for Transient Application
A ultra-wideband combined-oscillator antenna construction consisting of an electric monopole and a magnetic oscillator is described in this paper, based on energetic processes studying in the near-field radiator zone. The finite-difference time-domain method(FDTD) is employed to simulate the radiation properties of the combined-oscillator antenna. The numerical simulation results demonstrate that the designed antenna, which is excited by the mono polar pluse, has a symmetrical H-plane energy pattern about the axis with the cardiac type, and a asymmetric E-plane energy pattern about the axis with an up-shift of 30°, as well as a good voltage standingwave ratio(VSWR) property over 100 MHz-1600 MHz frequency band. This kind of antenna has simple construction, relatively small size and perfect performance for transient application, is ideally adapted to be used as a steering antenna array element that radiates the UWB electromagnetic pulse.
