Abstract: The paper described the design and performance analysis of log periodic dipole antenna at frequency 1800MHz -2500MHz (Ultra High Frequency Band), the antenna has been modeled using ADS layout and the S parameter was presented. A good impedance match in a wide frequency range has been achieved by a suitable choice of the antenna feeder impedance. The radiation pattern, Directivity, Return loss, Voltage Standing Wave Ratio (VSWR) and Gain are in accordance with the desired valuesare presented.
Keywords:LPDA (Log Periodic Diploe Antenna), Agilent.

Abstract :Significance of ICTs for sustainable development was examined arising from the fact that it has been put into the mainstream of development in Nigeria. It is a known fact that Information and Communication Technology (ICT) is an indispensible part of the contemporary World, therefore its revolutionary potentials cannot be over-estimated. In recent years, developing Countries like Nigeria and International development communities have started taking concrete actions to incorporate Information and Communication technologies (ICTs) into their economic policies and development goals.
Key words: Information, Communication, Technology, Sustainable and Development

Abstract:Interest involves the review of information technology in engineering for sustainable development. This takes a look at the relevance of information technology in Engineering with reference to the several form of information exchange between two or more computers through any of the several methods of interconnections. In modern global economy like Nigeria, I.T are intensively utilized for electronic transactional processing and in supporting various fields like banking, governance, engineering, health, education research fields and education in accomplishing their global and economic task across the nation. The emergence of the global information infrastructure presents extra opportunities challenges for the country. The use of mobile phone in the banking industry, its economic implications, and in general a systematic look into the various forms of mobile banking with emphasis on the security measures that makes the whole process safe for adoption will be outlined with reference to the technology being discussed.
Key words: I.T Technology, Engineering, and sustainable development.
