Abstract
Measurements using a composite primary feed with parasitic auxiliary elements reveal that both the copolar and crosspolar performances of this feed are better than those of the similar feed employing derived elements. An improvement of 10 dB in the crosspolar peak over that of the single dipole feed was obtained. An increase in antenna gain of about 3.3 dB was measured with a 3 dB suppression in sidelobe level.
