1. The problem statement, all variables and given/known data Determine the effective area (Aeff) for a short dipole with L = λ/60 and λ/2 dipole. If the wires used for dipoles has radii a = 1 cm compare Aeff with the physical area. G(short dipole) = 1.5 G(half wave dipole) = 1.64 2. Relevant equations Aeff = G* λ2/4*pi 3. The attempt at a solution Aeff = 1.64* λ2/4*pi = L2/pi * 1.64 = 0.052L2 Aphysical = pi*(a2 + a*L) = pi*10-4 + 1*10-2*L What is confusing me is that I cannot seem to get a numerical answer for this problem even though it is apparently possible. I'm sure I just keep over looking something simple and making this easy problem harder than it has to be.
