摘要:A dual polarized antenna couplet, comprised of a vertical quarter- wavelengthradiator driven at its lower end and centered on a half- wavelength horizontal dipoleradiator drooping its ends about 45° from the center where it is driven in phase with thevertical radiator, produces a polarized wavefront at an angle between the vertical and thehorizontal, such as 45° when both are driven equally, with 1. 5 db bi-directional gain in thehorizontal pattern and in the vertical pattern as well. A similar parasitic couplet is used asa reflector behind the driven couplet, and two or more parasitic couplets are used asdirectors in front of the driven couplet. The elements of the antenna are coated withdielectric material to achieve a shortening effect of about 11% over the normal lengthsof the antenna elements otherwise required.
