Abstract
This letter presents a new approach for the design ofa multiresonant printed bowtie antenna. Several techniques wereattempted to obtain one antenna which is operational in the 2, 3,and 5 GHz bands corresponding to many wireless applications.The idea of creating different slot configurations on different partsof a single antenna is the basic principle. A prototype of the finalantenna design was fabricated tested and a good agreement wasfound between simulated and tested results.

DIPOLE ANTENNAS

radiation is independent of  (rotationally symmetric about
the z axis). Dipole antennas and arrays of dipoles are commonly
used for high-frequency (HF) and ultrahigh-frequency
(UHF) communications, TV, and FM broadcasting, and as
electric field probes. This article will describe the basic nature
and applications of dipole antennas and some of their variations
such as biconical and bowtie antennas, slot dipoles,
folded dipoles, sleeve dipoles, and shunt-fed dipoles. The commonly
used broadband l ....etc

Discovery of Periodic Patterns in Spatiotemporal Sequences- IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERING, VOL. 19, NO.

java


Abstract—
In many applications that track and analyze spatiotemporal data, movements obey periodic patterns; the objects follow the same routes (approximately) over regular time intervals. For example, people wake up at the same time and follow more or less the same route to their work everyday. The discovery of hidden periodic patterns in spatiotemporal data could unveil important information to ....etc

The inkjet printing has grown into a mature noncontact patterning method in the recent times. With this method, large-area patterns can be easily created with high speeds while using only small amounts of functional materials and also high resolution can be achieved. RFID tags, organic thin-film transistors OTFTs and electrochromic devices ECDs are the major areas employing the method of inkjet printing. The future of plastic electronics is focussed on this technology.

Low-resistance printed conductors crucial for the development of ultra-low cost electronic systems such as radio frequency identification tags. Low resistance conductors are required to enable the fabrication of high-Q inductors, capacitors, tuned circuits, and interconnect. Furthermore, conductors of appropriate work function are also required to enable fabrication of printed Schottky diodes, necessary for rectification in RFID circuits. Last year, we demonstrated the formation of low-resistance conductive printed structures using gold nano pa ....etc
