The impedance of the slot antenna ( Z S) is related to the equivalent dipole ( Z D) by: Z S Z D = η 2 4. where η is the impedance of free space, about 120πΩ. So if the impedance of a long, thin, half-wave dipole is about 72Ω, then a long, thin slot has an impedance of about: ( 120 π Ω) 2 4 ⋅ 72 Ω ...
