| 20110159667 | SEMICONDUCTOR DEVICE MANUFACTURING METHOD - A method for fabricating a semiconductor device according to the present invention includes the steps of: growing a p-type gallium nitride-based compound semiconductor layer by performing a metalorganic chemical vapor deposition process in a heated atmosphere so that the crystal-growing plane of the semiconductor layer is an m plane (Step S | 06-30-2011 |
| 20110234466 | ANTENNA ELEMENT-WAVEGUIDE CONVERTER AND RADIO COMMUNICATION DEVICE USING THE SAME - An antenna element-waveguide converter includes an antenna substrate having, on one surface, an antenna element and rectangular metal plates arranged in a plurality of rows to surround this antenna element, and a waveguide having, at one end, an opening opposed to the one surface of the antenna substrate. Surfaces of the rectangular metal plates and the opening of the waveguide are arranged with a predetermined gap left therebetween in a direction perpendicular to the one surface of the antenna substrate. Thus arranging the antenna substrate and the waveguide avoids a stress due to assembly variations, which can achieve favorable antenna characteristics. | 09-29-2011 |
