Abstract: An antenna structure includes a main ground plane, a protruding ground plane, a feeding radiation element, a connection radiation element, a shorting radiation element, a first radiation element, and a second radiation element. The protruding ground plane is coupled to the main ground plane. The feeding radiation element has a feeding point. The connection radiation element is coupled to the feeding radiation element. The connection radiation element is further coupled through the shorting radiation element to the protruding ground plane. The first radiation element is coupled to the feeding radiation element. The second radiation element is coupled to the connection radiation element. The protruding ground plane further includes an extension portion. The first radiation element is adjacent to the extension portion of the protruding ground plane.

Abstract: An antenna structure includes a ground element, a first radiation element, a second radiation element, a third radiation element, and a nonconductive support element. The first radiation element is coupled to a first grounding point on the ground element. The second radiation element has a feeding point. The second radiation element is adjacent to the first radiation element. The third radiation element is coupled to a second grounding point on the ground element. The third radiation element is adjacent to the second radiation element. The first radiation element, the second radiation element, and the third radiation element are disposed on the nonconductive support element. The second radiation element is at least partially surrounded by the first radiation element. The third radiation element is at least partially surrounded by the second radiation element.

Abstract: The invention provides a spacer structure and a method of forming the spacer structure for providing uniform spacing between two transparent substrates of a Liquid Crystal Display. The spacer structure uses positive photoresist pads formed on opaque pads. The opaque pads are formed on one surface of one of the transparent substrates. The positive photoresist pads are formed using the opaque pads as a mask when exposing a layer of positive photoresist. The positive photoresist pads are self aligned to the opaque pads. The self alignment of the positive photoresist pads with the opaque pads make it possible to form several layers of positive photoresist pads on each opaque pad to achieve the desired spacer height.
