In this paper, Design of a reconfiguration frequency full metal case antenna with portable wireless terminal unit is presented in the Fig. 1. The prototype antenna in fabricated is used a copper sheet of 0.6mm thickness while occupies a volume of 13mm × 70mm × 0.6 mm, and suitable to be built-in housing of a mobile phone. A FR4 substrate with a thickness of 0.8 mm, relative permittivity of 4.4, and...
Built in Bluetooth wireless transmission allows easy GPS sensitivity record on the go without the hassle of external USB connections and wire cable anytime, anywhere. The mobile phone under test of far-field range testing has been the plan at the Cellular Telecommunications & Internet Association (CTIA) certification program test requirements for performing receiver performance measurement.
A high performance wire monopole antenna fabricated using two folded and meander wires as radiator is presented. A prototype of the proposed monopole antenna with a compact area size of 46 mm ?? 10 mm ?? 9 mm is implemented, and the antenna shows a wide operating bandwidth of about 273 MHz and 557 MHz for low band and high band bandwidth, making it easy to cover the GSM, EDGE, CDMA, CDMA 2000, W-CDMA...
The mobile ad hoc networks (MANET) is autonomous, infrastructureless network. Unlike the common Web service used in wired applications, the web service applications based on MANET have so many differences in data transmission, service registration and service discovery. All components of web service of MANET need to consider the features of mobile devices and mobile environment. Considering the characters...
