Abstract: An outlier IC detection method includes acquiring first measured data of a first IC set, training the first measured data for establishing a training model, acquiring second measured data of a second IC set, generating predicted data of the second IC set by using the training model according to the second measured data, generating a bivariate dataset distribution of the second IC set according to the predicted data and the second measured data, acquiring a predetermined Mahalanobis distance on the bivariate dataset distribution of the second IC set, and identifying at least one outlier IC from the second IC set when at least one position of the at least one outlier IC on the bivariate dataset distribution is outside a range of the predetermined Mahalanobis distance.

Abstract: A wireless internet with a plane antenna, the plane antenna comprises a plane, an import and an export antenna and plural radiators. The import antenna has a first and a second import line which connect with each other and an included angle is formed between the second and the first import line, the export antenna has a first and a second export line which connect with each other and the included angle is formed between the second and the first export line. The radiators are disposed between the import and the export antenna, each radiator having a first and a second conducting wire, a sharp part, a first and a second protruding fringe and a fillister. The radiators are divided into two symmetrically arranged teams. The connected angles between two neighboring radiators in the one of the teams are different.

Abstract: A wireless internet with a plane antenna, the plane antenna comprising: a plane, an import antenna, a plurality of radiator and an export antenna. The plane has an edge; the import antenna is located the plane, the import antenna has a first import line and a second import line, a point of the first import antenna connects with the edge, and the point is perpendicular to the edge, the second import line and the first import connect with each other to have an included angle; the plurality of radiator has a preview arrangement method to connect with the plane, each radiator has a first conducting wire, a sharp part, a first protruding fringe, a fillister, a second protruding fringe and a second conducting wire; the export antenna is located the plane, the export antenna has a first export antenna and a second export antenna, the second export line and the first export line connect with each other to have the included angle.
