Dipole aperture is the capture area which translates an incident field, in W/m^2, to the actual power received by the dipole. For example the aperture for a half wave dipole is 0.13(Lambda)^2, where Lambda is the wavelength in meters. A 40 m half wave dipole would therefore have an aperture of 52 m^2. A horn aperture, and also a parabolic dish, aperture is the physical area of the mouth of the horn. Regards. Frank Well, I sure read _that_ wrong! Thanks for clearing that up. |
