In this paper we discuss a number of UHF/RFID tag designs including the hybrid loop (Chen and Hsu, International Symposium on Antennas and Propagation, Korea, Vol. 3, 2005, 1045-1048), dual crossed-dipoles, the dual crossed-dipoles utilizing an inductively ...
In this paper the mechanical design of the new active MHD antennas for JET is described and the structural/mechanical analysis for the antennas is presented. These new antennas replace the existing n = 1 or 2 saddle coils with a set of eight smaller antenn ...
Chiral BINOL phosphorochloridites were esterified and amidated with enantiopure 6-hydroxytropinone [6-hydroxy-8-azabicyclo[3.2.1]octan-3-one] cyclic acetal to yield chiral bidentate and monodentate phosphite-phosphoramidite ligands for copper-catalyzed asy ...
The paper discusses the performance of a MIMO-extended UMTS-FDD downlink with a 2x2 and a 4x4 antenna configuration. An analytical expression for the average signal to interference ratio (SIR) of a space-time (ST) RAKE receiver in an interference dominated ...

A dual-polarized, broadband antenna made up of two single-polarized dipoles is presented. The antenna is mounted on a ground plane to produce a low-profile structure. Two fractal-like elements are used, but a very wide bandwidth is only achieved by making ...
The analysis of the dynamic behavior of power transmission line and telecommunication towers is of interest in protection and EMC studies related to lightning. Usually, time-domain surge impedance is used to characterize tower dynamic behavior. The main dr ...
A new, compact way to match slot antennas to a coplanar waveguide (CPW) feed is presented. In addition to its advantages of flexibility, reduced size, and increased bandwidth, a good analytical approximation of the matched antenna behavior is possible. An ...
This paper reports the fabrication and electrical characterization of high tuning range AlSi RF MEMS capacitors. We present experimental results obtained by a surface micromachining process that uses dry etching of sacrificial amorphous silicon to release ...
This paper addresses the problem of training sequence design for multiple-antenna transmissions over quasi-static frequency-selective channels. To achieve the channel estimation minimum mean square error, the training sequences transmitted from the multipl ...
