Antenna is transducers (it converts one from of energy in to another) that transmit or receive electromagnetic waves (has electric and magnetic field component which oscillate in phase perpendicular to each other and to the direction of energy propagation).

Radiated field nearest to the antenna Only radiation field exist in this region
