Abstract
Official abstract text for this publication.
A second slit 117 and a fourth slit 119 provided in a first antenna element 150 and a first slit 116 and a third slit 118 provided in a second antenna element 151 are adjusted such that the mutual coupling between the first antenna element 150 and the second antenna element 151 in the desired frequency band is canceled, and reduces degradation in coupling between antenna elements without connecting the antenna elements through components and the like. With such a configuration, it is possible to achieve high-efficiency loosely coupled MIMO array antennas operating in the same frequency band in a portable wireless terminal.
First claim
Opening claim text (preview).
The invention claimed is: 1. An antenna device comprising: a casing; a circuit board that is provided in the casing and has a ground pattern; a first antenna element that includes a first conductor plate which is disposed in and near the casing and is conductive and substantially rectangular, a second conductor plate which shares one side of the first conductor plate in a widthwise direction thereof, is disposed on the first conductor plate at approximately 90 degrees, and is…
