A printed compact S‐shaped monopole antenna for penta‐band mobile phone application is presented. The S‐shaped monopole antenna has a uniplanar structure and can be printed on an FR4 substrate of small size 10 × 45 mm 2 to achieve a compact configuration. By mounting the antenna above the top edge of the system ground plane of the mobile phone and feeding it using a perpendicular feed, the antenna occupies a small volume in the top portion of the mobile phone. This makes it especially suited for application in the thin mobile phone in which the embedded internal antenna is required to be small in occupied volume and narrow in width. In addition, the antenna can generate two wide operating bands at about 900 and 2000 MHz to cover the GSM850/900 and DCS/PCS/UMTS operation, respectively. Details of the proposed antenna are presented.
