Summary:An antenna system comprises a first antenna element adapted to a first frequency band and a second antenna element adapted to a second frequency band different from the first frequency band. The first antenna element includes a radiating structure having a planar radiating element and configured to radiate at a frequency in the first frequency band and a band-stop filter having a planar conductive element and configured to attenuate a current flow at a frequency in a second frequency band different from the first frequency band. The planar conductive element is arranged in a meander pattern, has an end electrically connected to the planar radiating element, extends in a direction substantially parallel to the planar radiating element, and has an electrical length substantially equal to ¼ of a wavelength of the frequency in the second frequency band.
