UHF fading in factories
There has been recent interest in characterizing UHF propagation within buildings and houses. Factory radio channels, however , have not been discussed previously in the literature. This paper details the results of narrow-hand propagation measurements performed at five factories. The extensive empirical data indicate that path loss is dependent upon local surroundings and is log-normally distr...
متن کاملUHF RFID Reader Antenna
This chapter addresses the various design issues, requirements, and specifications in designing reader antennas for UHF RFID applications. In a typical UHF system, the RFID reader antennas are geography specific; that is, there are different antennas for different geography, namely North America, Europe, et cetera. The discussion on the design challenges and performance expectations lead to a n...
متن کاملOn Stripline Y.Circulation at UHF*
The simplified boundary-value problem of the circular strip-line Y-circulator is stated and, following experimental results, is solved approximately. The circulation parameters are calculated and dkcussed. The frequency characteristics are evaluated and a general method for broadbandhtg the device is presented. From the calculated and measured field distribution, an explanatory description of t...
متن کاملUHF RF Transmitter and Receiver
Here we propose a current mode oscillator circuit using Q-Dot technology and subsequently we modify this circuit for transmitter and receiver design. We like to note that transmitter is a amplitude modulation (AM) to frequency modulation (FM) conversion technique. The receiver is of Super heterodyne structure, where the RF front end is implemented by Q-Dot devices and the IF stages are implemen...
متن کاملInterference on UHF SATCOM Channels
The Mobile User Objective System (MUOS) will replace the existing ultra high frequency (UHF) Follow-on (UFO) constellation beginning in 2007. It is expected that the MUOS will use the roughly 8 MHz of UHF spectrum currently allocated to the DoD. In most NATO countries, this bandwidth is reserved for SATCOM but in other parts of the world, it is allocated on a primary basis to terrestrial commun...
