VTC Fall - Performance Analysis and Implementation of a New Position Location System Using DTV TxID Watermark
IEEE Vehicular Technology Conference, 2006Co-Authors: Xianbin Wang, Yiyan Wu, Gilles Gagnon, Jean-yves ChouinardAbstract:Performance of a new position location system using the transmitter identification (TxID) RF watermark in the digital TV (DTV) signals is analyzed in this paper. Compared to the Global Positioning System (GPS), DTV signals are received from transmitters at relatively short distances, while the broadcast transmitters operate at levels up to a few megawatts of Effective Radiated Power (ERP), which makes the new position location system very robust even inside buildings. Practical receiver implementation issues including non-ideal correlation function and frequency synchronization are analyzed and discussed. New algorithms of removing the bandlimitation effect and frequency synchronization are proposed. Performances of the proposed techniques are evaluated through analysis and Monte Carlo simulations. Possible ways to improve the accuracy of the new position location system are discussed.

A novel approach for gain and bandwidth enhancement of patch antennas
Proceedings RAWCON 98. 1998 IEEE Radio and Wireless Conference (Cat. No.98EX194), 1998Co-Authors: Yongxi Qian, D. Sievenpiper, V. Radisic, E. Yablonovitch, T. ItohAbstract:The microstrip patch is one of the most preferred antenna structures for low-cost and compact design of wireless communication systems and RF sensors. To overcome several intrinsic limitations of the patch antenna such as narrow bandwidth, low gain, and degradation of radiation efficiency at higher frequencies, we propose a novel technique for gain and bandwidth enhancement based on the photonic band-gap (PBG) concept. The Ku-band prototype demonstrates over 3 times bandwidth improvement, and 1.6 dB higher gain or 45% increase in Effective Radiated Power (ERP), compared with a regular patch with identical dimensions. System design issues such as co-site interference can also be alleviated by the improved beam patterns of the new PBG antenna.

IEEE International Digest on Microwave Symposium, 1990Co-Authors: A. Mortazawi, T. ItohAbstract:A periodic second-harmonic spatial Power combining oscillator is designed and fabricated. This circuit does not require an external resonator. It is planar, and therefore it makes the design of monolithic circuits easier. In this work, four X-band Gunn diodes are used. The Effective Radiated Power is 370 mW at 18.6 GHz. The isotropic conversion efficiency is 10.2%.

Spatial Power combining using push-pull FET oscillators with microstrip patch resonators
IEEE International Digest on Microwave Symposium, 1990Co-Authors: J. Birkeland, T. ItohAbstract:The design and performance of spatial Power combining arrays of FET oscillators are described. The individual oscillators consist of single microstrip patches driven by two FETs oscillating in the push-pull mode. Arrays formed from these elements show nearly perfect Power combination in prototype modules operating at 6 GHz. Maximum Effective Radiated Power (ERP) for a four-patch array combining the Power of eight FETs is 32.8 dBm. Results for an oscillator using four FETs combining in a single patch are also discussed.
