Abstract

Limits are derived on the maximum amplitude of the antenna impulse response and its derivative, for the general case and for the special cases of constant directivity and constant effective aperture. It is shown that in general the maximum feasible amplitude is directly proportional to the square root of maximum antenna directivity, but proportional to the logarithm of the bandwidth ratio. Comparisons with published impulse response data show that measured and simulated data are compatible with the computed limits.
