    摘要: Provided are a conductive structure for a high gain antenna and an antenna. A plurality of conductive patterns (512) of the conductive structure are formed on top and bottom surfaces of a dielectric substrate (511) positioned above the antenna and separated from an antenna body (500). A conductive upper structure of the antenna (510) is positioned above the antenna opposite to a ground plane (530) to which the antenna body is fed, separated from the antenna body. A conductive unit structure comprising a plurality of conductive patterns (512) formed on top and bottom surfaces of the dielectric substrate (511) is arranged in a plurality of layers. The conductive structure for a high gain antenna and the antenna can be readily produced by using low cost printed circuit board (PCB) technology, and a gain of the antenna can be increased regardless of a resonance distance between the ground plane of the antenna and the conductive structure disposed above the antenna.

    摘要: The invention is directed to compositions and methods for selectively reducing the expression of a gene product from a desired target gene in a cell, as well as for treating diseases caused by the expression of the gene. More particularly, the invention is directed to compositions that contain double stranded RNA (“dsRNA”), and methods for preparing them, that are capable of reducing the expression of target genes in eukaryotic cells. The dsRNA has a first oligonucleotide sequence that is between 25 and about 30 nucleotides in length and a second oligonucleotide sequence that anneals to the first sequence under biological conditions. In addition, a region of one of the sequences of the dsRNA having a sequence length of at least 19 nucleotides is sufficiently complementary to a nucleotide sequence of the RNA produced from the target gene to trigger the destruction of the target RNA by the RNAi machinery.
