Call for Papers
The 15th annual IEEE Wireless and Microwave Technology
Conference (WAMICON 2014) will be held in Tampa, Florida
on June 6, 2014. The conference will address up-to-date
multidisciplinary research needs and interdisciplinary aspects
of wireless and RF technology. The program includes both oral
and poster presentations. t t
Topics of interest include:
Emerging RF and Microwave Technologies
Biomedical Applications, Wireless Sensing, Energy Harvesting,
Wireless Power Transfer, Terahertz Technologies, Nano Devices
and Circuits. Other emerging wireless and microwave topics will
also be considered.
Cognitive Radio, 4G and Advanced Data Networks,Ultra-Wideband (UWB), MIMO, Multi-Carrier, Spread Spectrum,
Channel Characterization and Modeling and Software Defined
Radios (SDR). Additionally, papers on Point-to Point and
Point-to-Multipoint Systems including MESH Sensor Networks
will be considered.
Authors are asked to submit papers electronically in .PDF
format. To be considered for publication, an initial submission of
3 pages, clearly describing the concept and results must be
submitted prior to February 14, 2014 deadline. Final manuscript
of 3-6 pages will be requested only after paper acceptance.
Submissions will be evaluated for originality, significance of the
work, technical soundness and interest to a wide audience.
Visit www.wamicon.org for complete details of submission.

small size to some extent. To demonstrate the feasibility
and validity of the design equation, a miniaturized balun
filter, with the size of 3× 21 mm, is designed and fabricated
on a PCB substrate. The electrical length of the coupled
lines for the fabrication could be chosen as short as 15°.
The measurements agree well with the simulation results.
This class of balun filter is expected to be invaluable in the
design of miniaturized balanced microwave circuits. ■
