A Triangle Array of 1× 4 Slots Antenna with Curved EBG Structures for Cellular Base Station Rangsan Wongsan* and Paowphattra Kamphikul Abstract—In this paper, a slot array with a new technique of metamaterial on Electromagnetic Band Gap (EBG) structure is used to demonstrate the possibility of building high gain top-mounted Resistor Loaded EBG Surfaces for Slot Antenna Design Slot antenna is placed within the REBG surface. The REBG surface is used to suppress surface waves across the antenna aperture, resulting in radiation performance improvement. Concurrently, the REBG surface can also absorb electromagnetic energy to reduce antenna radar cross section (RCS).
Slot antenna - Wikipedia A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. The shape and size
