RT Journal Article ID 0fcf23f653d52850 A1 Gorobets, Yu. N. T1 Scattering coefficient of circular-aperture antenna JF Telecommunications and Radio Engineering JO TRE YR 2002 FD 2007-03-19 VO 57 IS 6-7 OP 7 AB The relationship between the scattering coefficient of an aperture antenna and the type of amplitude distribution and dimensions has been studied. It is shown that there exist optimal conditions for antenna excitation under which the maximum directivity-to-scattering coefficient ratio is provided.
