The present invention discloses a method of forming a multi-band antenna, especially the fractal antenna which allows a convenient reception of single for communication. The multi-band behavior is obtained by a set of geometry patterns of the same basic elements. The antenna is formed by preparing coating particles including particles, silica, and a solvent. Heating the metallic particles, the silica particles and the solvent at a temperature higher than about 100 degrees C. to from a coating solution. An additional passive layer can be added to protect the conducting layer of the antenna. Materials for this passive layer are made, for instance, of oxide.
