Dear Sir

Follow the following steps:

1- show the current distribution on the Antenna surface using any simulation suite

2- the best location of the slot is at the positions where the current is concentrated

3- the shape of the slot should be selected to be perpendicular to the direction of the current.

4- the length of the slot is either (guided wavelength/2) for short circuited slot or (guided wavelength/4) for short-open circuited slots.

Good Luck
