Abstract: An antenna 1 includes: a plate-like base 3 made of an insulating material; and a conductor 5 in a predetermined shape, which has multiple cut-out portions 10, 13, 15 and which is provided at a predetermined position of the base 3 to obtain predetermined antenna characteristics. The antenna 1 is configured so that the antenna characteristics can be mostly maintained even when the base 3 is deformed into a predetermined curved-surface shape.

Abstract: According to the invention, a document is created through steps of inputting handwritten characters by the use of a mouse or a pen-tablet, recognizing the inputted characters, and determining to use the characters. A transparent virtual window is created on a screen of a display device. In the transparent virtual window, continuity is established between upper and lower boundaries and between left and right boundaries of an input region so as to remove upper, lower, left, and right frame boundaries which would otherwise limit the input region. A handwritten character is inputted and displayed on the thus-created transparent window. Accordingly, a visually handicapped person can input characters on a personal computer in a simple manner.
