Abstract :
A suitable definition for the vector effective length of an arbitrary slot receiving antenna placed in a large conducting plane is presented, and a general formula is obtained for its derivation. To derive the definition and formula, the effective length of a general wire antenna is derived, and then an analogous method is applied to the slot problem. The relationship of the slot´s effective length to that for a flat strip wire antenna driven by a specified current is obtained. Formulas for the lengths of some specific common slot antennas are derived from the general expression. The current sampling property of a small straight slot is discussed
