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.

Multi-band antenna

The portable device comprises a control IC imbedded in the portable device and a RF module coupled to the control IC for wireless communication. A display and an input unit are coupled to said control IC. Memory is coupled to the control IC to store data and a projection display module is coupled to said control IC for the data projection. The projection display module includes three liquid crystal panels that perform image displays in red, green, and blue, respectively; light emitting sources employed and positioned in correspondence with the liquid crystal panels, respectively. A dichroic prism is used for each display color combination, wherein the liquid crystal panels and the said light emitting sources are positioned on the light-incidence side of the side surfaces of said dichroic prism. A projection lens is provided on the light emission side of the dichroic prism.
