Abstract Two internal antennas for GSM/DCS and WLAN operations printed and integrated on a dielectric substrate for application in a dual‐network PDA phone are presented. The two integrated antennas are printed PIFAs mounted at the top edge of the main circuit board of the PDA phone, and the isolation behavior of the two antennas with various possible arrangements is studied. The optimized isolation between the two antennas is analyzed. Over the GSM, DCS, and WLAN bands, good isolation (less than −20 dB) between the two integrated antennas can be obtained. © 2005 Wiley Periodicals, Inc.
