In this paper, two methods of shielding effectiveness (SE) measurements in a partially anechoic chamber are presented. The first measurement method is based on measuring S21 parameters using the network analyzer. In the second method, the spectrum an
This paper considers numerical and experimental models of an enclosure, with a printed dog-bone dipole antenna structure inside. This printed structure is placed inside the enclosure in order to improve its protective function. An improvement of shie
