Correction to "A low-profile wide-band (5:1) dual-pol array"

In the abovementioned letter [ibid., vol, vol. 2, pp. 46–49, 2003], there was an error in the caption of Fig. 2. The caption should read as follows. Fig. 2. Input match (radiation efficiency) of the element. Efficiency improves as the array size increases (compared to wavelength). Top two curves are measured data for an L-band element (11-cm spacing), while the bottom curve refers to an infinite array with data computed by HFSS software based on unit cell model. Dip at 2 GHz is caused by coupling of adjacent elements (through the gap).
