<p>A perforated strip, in which the dimensions of the holes and the spacing between them are small compared with the wavelength at which the device operates, gives low inductance when used to contact microwave devices. The holes are typically 17 mu square on 35 mu centres. The grids are prepared by the electrolytic deposition of a suitable conductor such as gold, through photoengraved holes in a photosensitive material, onto a thin metallic film supported on a flat substrate. The substrate is later removed by etching. Inductances of less than 25nH at 9 GHz were obtained.</p> |
