Abstract :
An internal multi-band antenna for mobile phones featuring wide fractional bandwidth is presented. The antenna is realized by a flat conformal conductor above the ground plane, featuring a feed and ground connections to the PCB. A slot is cut in the flat conductor, which is open only in between the ground and feeding connections of the flat conductor, thus forming a slit. This structure is called enhanced bandwidth folded inverted conformal antenna (EB-FICA), with reference to its precursor FICA (Di Nallo and Faraone, 2005). The EB-FICA can be designed to be penta-band, covering the four GSM bands and the UMTS Rx band, and has been adopted in several Motorola products.
