Abstract
A printed-on-display (POD) antenna is mounted on a wireless mobile personal terminal. The POD antenna is formed of conductive transparent material such as indium oxide doped with tin oxide (ITO). The POD antenna is printed on a glass substrate of display of the personal terminal by physical vapor deposition (PVD) or chemical etching. Pattern of the POD antenna is configured to have a radiation pattern the same as a conventional monopole antenna and an omni-directional characteristics. Hence, the POD antenna may be embedded, resulting in an elimination of drawbacks of conventional exposed antenna such as liable to damage, complex in assembly, and high in cost.
Claims10
A process for manufacturing a printed-on-display (POD) antenna of a wireless mobile personal terminal having a crystal liquid display (LCD), said process comprising the steps of:
- a) preparing a conductive transparent material;
- b) coating a uniform layer of said conductive transparent material on a glass substrate of said LCD;
- c) coating a photoresist layer on said conductive transparent layer;
- d) coating a mask having an antenna pattern on said photoresist layer;
- e) exposing said mask by ultraviolet (UV) rays;
- f) immersing said glass substrate in a developing solution for developing for removing said yet cured photoresist layer;
- g) etching said conductive transparent layer on said glass substrate;
- and
- h) cleaning said remained photoresist layer for forming a pattern of said POD antenna on said conductive transparent layer of said glass substrate.
