Abstract :
This paper presents the packaging solution for the microstrip part of the descrambling section of dual polarized Eleven antenna. The packaging solution is based on using artificial Perfect Magnetic Conductor (PMC) shielding instead of conventional metal shielding. The PMC shielding is realized with a metal pin surface, and these metal pins force the parallel plate cavity modes to vanish within the frequency range of interest, from 5 GHz to 13.5 GHz.
