Antennanordning med en transceiverkrets och en transceiveranordning med minst ett antennelement

摘要

A printed circuit board (10) carries a thin metal ground plane layer (11) on its front side and apertures (12) serving is radiating elements in order to couple high frequency electromagnetic power between a feed network on the rear side and a radiating patch (30). The feed network includes micro-strips (13) each associated with an aperture so that two orthogonally polarized microwave carriers with superimposed mobile telephone signals are transferred to the radiating patch, while shielding boxes (14) prevent backward radiation and propagation of radiation in a longitudinal direction on the rear side. AN Independent claim is included for an antenna assembly.
