This paper presents an internal dual-band patch antenna to be mounted above the system ground plane of the PDA (personal digital assistant) phone for GSM/DCS operation. The antenna is supported by conducting pins (5 mm long in this study) and mounted above the system ground plane of the PDA phone. In this case, the antenna does not directly occupy the system ground plane, and a usable space between the antenna ground portion and the system ground plane is provided for accommodating associated conducting elements or electronic components of the PDA phone. A design example is demonstrated, and obtained results are presented and discussed.
