    摘要： A surface lighting device has one single light source and a light-guide-board. The board includes a light-guiding-section and a light-emitting-section. A shorter side of the light-guiding-section is not more than 8 mm, and an area of the light-emitting-section is not less than 500 mm2. The light-emitting-section has the following features: (1) a ratio of min. luminance vs. max. luminance is not less than 0.3; (2) an average luminance ranges from 1 cd/m2 to 200 cd/m2, and (3) a change in luminance per unit length is not more than (average luminance)×100 cd/m3. Employing plural light-emitting-elements in one light source allows the lighting device to produce versatile colors. The light source, light-guide-board and a holder are structured and shaped in optimum way, so that unevenness in luminance of the device is reduced. An LCD unit incorporating this surface lighting device increases its display quality, and a portable terminal incorporating this LCD unit produces easy-to-lead display.

    摘要： An antenna device includes radiation elements formed on a common antenna board, a feeding unit for feeding the radiation elements, and a ground plate provided in electrically-spaced relation to the radiation elements. The ground plate is mounted on a box-like metal body to form a short-circuit therewith. The radiation elements may have different line lengths for transmitting and receiving a plurality of wavelengths. The feeding unit may include a first radiation element having a different electrical length than a second radiation element, a first feed point for feeding electric power to the first radiation element, and a second feed point for feeding radiation elements are grounded to the ground plate at respective first and second ground points. The difference from the first and second feed points to their respective ground points are different from one another.
