摘要

本文介绍了在一种空对空雷达模式下，利用次优平面共振偶极子元件辐射超宽带脉冲的研究。用短于天线物理长度的脉冲激发偶极子，推导出与天线辐射机理有关的重要特性。时域有限差分法的仿真结果表明，通过对谐振偶极子的物理结构进行微小的改变可以减小脉冲畸变。

Investigation of planar resonant dipole antennas for continuous-wave and ultra-wideband radar modes

This paper presents an investigation into the use of suboptimal planar resonant dipole elements to radiate ultra-wideband pulses in the context of a proposed air-to-air radar mode. By exciting a dipole with a pulse that is shorter than the physical length of the antenna, important properties relating to the radiation mechanism of the antenna are deduced. The results of simulations using the finite-difference time domain method reveal that pulse distortion can be reduced by making small changes to the physical structure of the resonant dipole.
