Thin internal planar antenna for GSM/DCS/PCS/UMTS operation in a PDA phone

A novel thin internal planar antenna for GSM/DCS/PCS/UMTS quad-band operation in a PDA (personal digital assistant) phone is presented. The proposed internal antenna has a small thickness of only 3 mm, yet it is capable of providing two wide operating bands at about 0.9 and 2 GHz so as to meet the bandwidth requirements of the GSM/DCS/PCS/UMTS systems. Details of the design considerations of the proposed antenna are described, and the experimental results of the constructed prototype are presented. © 2005 Wiley Periodicals, Inc.
