Abstract :
The advent of new, multi-standard mobile phone devices is a real challenge for antenna designers, as they have to implement integrated multiband operation within a volume which is rapidly shrinking. Some investigations concerning the input return loss, field distribution and efficiency of a novel internal, quadband patch antenna are presented. With a combination of metallic patches and slots, four different standards can be covered with one single, small antenna.
