Patent ID: 7999743

Claim:
A multiband antenna array for a mobile radio equipment, comprising: a planar patch antenna defining a plane and having a first branch that resonates in a first frequency band and a second branch that resonates in a second frequency band and is further coupled to a ground connection and to a high-frequency interface, the planar patch antenna having a first side and a second side, the first side being adjacent to the second side; and a plurality of parasitic transmitters, wherein said plurality of parasitic transmitters are located (i) marginal to the planar patch antenna, (ii) outside of the planar patch antenna, and (iii) in the plane defined by the planar patch antenna, wherein: (i) each of the plurality of parasitic transmitters are embodied so as to be free of said high-frequency interface; (ii) said plurality of parasitic transmitters are arranged as line-shaped conductor structures; and (iii) at least one of said plurality of parasitic transmitters which forms a bend includes: (a) a first three dimensional line-shaped portion that extends in a first dimension in the plane, the first three dimensional line-shaped portion running parallel to the first side; and (b) a second three dimensional line-shaped portion that extends in a second different dimension in the plane, the second three dimensional line-shaped portion running parallel to the second side, wherein conductor structures of the planar patch antenna are arranged as sheet-shaped conductor structures.
