ANTENNA SYSTEM AND ANTENNA MODULE WITH REDUCED INTERFERENCE BETWEEN RADIATING PATTERNS

摘要

The invention relates to an improved antenna system and antenna module incorporating same. The antenna system comprises: a first antenna element adapted to a first frequency band; and a second antenna element adapted to a second frequency band which is different from the first frequency band. The first antenna element includes: a radiating structure comprising at least one planar radiating element, where the radiating structure is configured to radiate at a frequency in the first frequency band. The first antenna element further includes: at least one band-stop filter structure comprising at least one planar conductive element, where the at least one band-stop filter structure is configured to attenuate a current flow at a frequency in the second frequency band.
