摘要：

The paper describes a dual-polarized antenna array for Impulse Radio Ultra Wideband (IR-UWB) applications. Firstly a brief description of the single radiator is given. Next the prototype is presented and measured data is compared with the simulated one. The linear array consisting of four components achieves a very narrow mean 3 dB beam width, which is approx. 15 degrees in the FCC frequency range from 3.1 GHz to 10.6 GHz. The second main lobe of the array factor and the grating lobes are suppressed by the radiation pattern of the single element. The mean cross-polarization suppression in the main beam direction is larger than 20 dB. Next the simulated and measured time domain radiation properties of the antenna array are presented. The array is applicable in the polarimetric, impulse based ultra wideband systems with high angular selectivity and high range resolution.
