Hui-Ling Lan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: An antenna includes a substrate having a first layer, a second layer, a third layer and a fourth layer, and an antenna unit having a first pattern being of a substantially coiled shape and printed on the first layer, a second pattern being of a meandering shaped and printed on the second layer, a third pattern being of a meandering shaped and printed on a third layer, and a fourth pattern being of a substantially coiled shaped and printed on the fourth layer. The first pattern, the second pattern, the third pattern and the fourth pattern are of a serial connection. The free end of the first pattern connects a feeding point. The free end of the fourth pattern connects a grounding point. Thus, the antenna has advantages of compact size and low cost, due to the antenna unit printed on the substrate and the pattern of the antenna unit.
