Antenna inside PBG and Fabry-Perot cavities

Abstract : Photonic crystals are used quite frequently to enhance the antenna gain. To understand the origin of this enhancement we have assimilated the PBG-Antenna structure to a Fabry-Perot cavity, where the source of the incident plane wave is placed inside. The PBG reflecting surfaces are composed of periodic metallic wires. The Fabry-Perot interferometer is usually studied with an excitation source placed outside the cavity. Here we had to extract new formulas for the case of the sources positioned inside the cavity. These simple formulas are found to be very helpful and very precise compared to the exact FDTD simulation. In the second part of the paper a simple model of the antenna is proposed to take into account the interactions between the cavity waves and the
