Abstract
The invention relates to a method of producing a photonic bandgap structure on a slot-type microwave device which is produced on a metallized substrate. According to the invention, periodically-spaced patterns are formed on the surface of the aforementioned substrate opposite the surface comprising the slot. The invention is suitable for slot-type antennas.
