This paper presents the design and realization of a circularly polarized antenna for anti-drone applications. A broadband Archimedean spiral antenna is designed as a radiating element for circular polarization. A metamaterial ground plane is designed and used as a reflector for the spiral antenna. The extraordinary properties of metamaterial ground plane are used to transform the radiating element into high-gain, low-profile antenna. The unit cell for metamaterial ground plane is derived from the Mushroom-like Electromagnetic Band Gap (EBG) cell. The frequency band of operation of this cell is more than its parent cell........
