Patent attributes
A mobile terminal comprising: a casing with at least one body which has electronic means; an antenna arrangement having at least one antenna element (14) provided on or within said body or on or within at least one of several bodies of said casing in a defined spatial relation to a conducting chassis part (12) of the body or the respective bodies allowing a high frequency interaction between the antenna arrangement and the conducting chassis part, said conducting chassis part being limited by a periphery of the conducting chassis part. Said antenna element has at least one arm (16a, 16b) which extends outwardly of said periphery along at least one chassis part edge for promoting said high frequency interaction or/and that said antenna arrangement has at least two arms (16a, 16b) of different length which are provided by the same or at least two different antenna elements and which extend in different or opposed directions along at least one chassis part edge, wherein a shorter arm (16b) has an effective electrical length shorter than a quarter wavelength at a resonance frequency within the or a particular predetermined frequency band and a longer arm (16a) has an effective electrical length longer than a quarter wavelength at said resonance frequency, to improve the band width of said frequency band.
