Research ArticleOpen accessPhrase in the titleA Six-Port Reflectometer Calibration Using Wilkinson Power DividerTraii Moubarek, Ali GharsallahA new calibration method for a six-port reflectometer which minimizes the effect of power measurement errors is presented. It is based on the power divider correlator to obtain estimates of the six-port calibration constants. The calibration procedure is to determine the constants that govern the operation of the six-port from the measurement of power or output ports tensions by placing … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 17 Mar 2016 · 7,798 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLow Power Phase Locked Loop Frequency Synthesizer for 2.4 GHz Band ZigbeeNesreen Mahmoud Hammam Ismail, Masuri OthmanProblem statement: Wireless communication systems are required for many applications. There are different standards for these systems. IEEE 802.15.4 defines the communication system standard for zigbee. This study discussed designing one of the blocks of zigbee transceiver which is the Phase Locked Loop (PLL). A major target for any communication systems is saving battery power, especially for zigbee as it … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,057 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUsage of Lightning Arrester Line to Feed Light Electrical LoadsHani Bani Odeh, Yousif El-TousIn remote areas, light loads (tens of kilowatts) are scattered and situated in the field of high voltage lines (66KV and above). These loads are very far from the main feeders/sub-stations (33KV-0.380KV). Feeding such loads in the traditional ways like provision of Diesel-Powered Stations, installation of new distribution lines from the Feeding Centers, or building new Sub-Stations are not practical … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 8,228 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign and Development of Broadband Inverted E-shaped Patch Microstrip Array Antenna For 3G Wireless NetworkNorbahiah Misran, Mohammad Tariqul Islam, Ng Kok JiunnMicrostrip patch antenna has been received tremendous attention since the last two decades and now it becomes a major component in the development of Smart Antenna System for Third-Generation Wireless Network proposed by the ITU-R under the banner of IMT-2000. Smart antenna consists of an array of antennas associated with it a base-band hardware and control unit (inclusive of the … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,123 accessesView PDF Cite
