Abstract (en)
[origin: EP1267439A1] An antenna (1) is provided to operate in multiple frequency bands. The antenna (1) consists of a first antenna element (3) for receiving and transmitting signals in a first frequency band, and a second antenna element (7) for receiving and transmitting signals in a second frequency band. The first antenna element (3) has a substantially elongated conductor of a predetermined first pitch, which is coupled to a feed point (4). The second antenna element (3) has a substantially meandering coil of a predetermined second pitch, which is coupled to said feed point (4). The substantially meandering coil comprises a plurality of first portions (7a) having a wound form and surrounding at least partly said first antenna element (3) and also comprises a plurality of second portions (7b) having a straight form. Each first portion (7a) extends from an upper end of said second portion (7b) to a lower end of a subsequent second portion (7b) following in axial direction of the second antenna element. <IMAGE>
