Abstract

An internal shorted planar monopole antenna embedded with a resonant spiral slot for GSM850/900/DCS/PCS/UMTS operation in the mobile phone is presented. The planar monopole is printed on an FR4 substrate of small size 10 × 45 mm², and a spiral slot of length 108 mm is embedded therein. The planar monopole is then placed above and perpendicular to the top edge, with a small distance of 7 mm, of the system ground plane of the mobile phone to operate as an internal antenna. A coupled feed printed on the top no-ground portion of the system circuit board is used to excite both the planar monopole and the spiral slot to generate two wide bands covering GSM850/900 and DCS/PCS/UMTS operation, respectively. The antenna is also suitable to integrate with the associated electronic components, such as the speaker, to achieve a compact integration of the antenna inside the mobile phone. Experimental and SPEAG SEMCAD-X simulation results of the proposed antenna are presented. The user's hand effects on impedance and radiation characteristics of the antenna are also analyzed. © 2007 Wiley Periodicals, Inc.
