Internal GPS Patch Antenna

onderzoek PDF


This product specifications are applied to the antenna composed of silver pattern on the dielectric material surface and conducting mechanism for the GPS satellite communications. Comparing to the conventional patch antenna, the miniature size relative to the high gain and low axial ratio characteristics are the most advanced design for a commercial compact product applications. eg. mobile phone; PDA; note book ; personal tracker and etc.. .Please contact us when using this product for any other applications than described in the above.

*This design patents are pending from China, Taiwan, USA.
