Abstract

A promising printed loop antenna is described that can be mounted in perpendicular to the top edge of the system circuit board of the mobile phone for penta-band operation. The antenna comprises a loop pattern printed on a thin FR4 substrate of small size 10 X 60 mm² and a perpendicular feeding portion printed on the narrow top ungrounded region of the system circuit board. Since the top ungrounded region is 4 mm in length only, the antenna is very low profile to the top edge of the ground plane on the system circuit board; that is, the antenna occupies a small volume inside the mobile phone housing and is suitable to operate as an internal antenna. In addition, the antenna generates two wide operating bands centered at about 900 and 1900 MHz to cover GSM850/900 and DCS/PCS/UMTS operations, respectively.
