Abstract

A combination of aVivaldi slot (46) and a meander line loaded antenna (30) which exhibits an ultra wideband characteristic with de Vivaldi notch expanding the high end and with the meander line loaded antenna portion reducing the low frequency cut-off. When these antennas are arrayed, this array exhibits a single lobe and an ultra wide 100: l bandwidth. The Vivaldi notch portion of the antenna accommodates the higher frequencies, whereas the meander line loaded antenna portion of the antenna accommodates the lower frequencies, there being a smooth transition region between the Vivaldi and meander line portions of the antenna and no discontinuity. A polarity switchable embodiment (Figure 6A) and a concatenated embodiment (Figure 12) are also disclosed.
