Abstract :
A compact T-slit monopole antenna with slotted ground plane in the mobile phone for penta-band operation is proposed. In this configuration, the antenna comprises a T-slit monopole printed on the top ungrounded portion of an FR4 substrate of small size of 47 ?? 5.4 mm2 and a slotted ground plane etched on the back side of the substrate of size of 47 ?? 10 mm2. In addition, an inverted-L copper strip is soldered to the end edge of the monopole for extending the electrical length of the antenna for GSM band; that is, the proposed antenna occupies a small volume of 47 ?? 10 ?? 5 mm3 inside the mobile phone and is suitable to operate as an internal antenna. By controlling the related parameters, the proposed antenna can resonates at different operating bands to cover GSM850/900 and DCS/PCS/UMTS operations independently.
