Description
  • Small shielded boxes are nowadays widely used for measurement of EMS, EMI and sensitivity properties of different devices. This paper deals with an improvement of commercial small shielded box parameters for a measurement of sensitivity of small mobile devices in 650 MHz – 4 GHz frequency band. Optimization of shielded box parameters is obtained by an inner area modification. Suitable wideband equiangular spiral antenna was designed for this measurement. Parameters of antenna inside the box, such as gain, impedance, directivity etc. are discussed in the paper. Effects of antenna positions in the box for a transmission are shown and the best configuration of antennas placing for the transmission in the shielded box is chosen.

  • Malé stíniné boxy se dnes pou3ívají pro mioení EMS, EMI a citlivosti rozliených zaoízení. Elánek popisuje vylep1ení parametru komereni dodávaného malého boxu pro mioení citlivosti malých mobilních zaoízení v kmitoetovém pásmu 650 MHz – 4 GHz. Zlep1ení parametru stíniného boxu je dosa3eno modifikací vnitoního prostoru (stin). Pro toto mioení byla navr3ena vhodná 1irokopásmová samokomplementární spirálová anténa. O parametrech dané antény (zisk, impedance, smirovost atd.) uvnito boxu je pojednáno v elánku. Dále je uveden vliv pozice antény na poenos uvnito boxu a je nalezena nejlep1í konfigurace umístiní antén s minimálním vlivem na poenos. (cs)
