It is proposed that the application of defected ground structures (DGS) and electromagnetic bandgap (EBG) reduce the phase velocity, increase effective permittivity of microstrips and reduce the effective the wavelength which eventually lead to the reduction of overall length of Wilkinson power dividers. Furthermore, the adjacent strip lines may approach each other, which cause coupling problem...

Superharmonic injection locking is investigated in a new theoretical approach. Low power frequency dividers are designed using injection locked oscillators with cascode transistors. The Rockwell 0:5 m CMOS process is used to design a 3mW injection locked frequency divider in the 1800MHz frequency range. A 200MHz maximum locking range is achieved in simulations. 2SC3302 TOSHIBA NPN transistors a...

This work describes the design of a divder technique Low-power techniques are applied in the design of the unit, and energy-delay tradeoffs considered. The energy dissipation in the divider can be reduced by up to 70% with respect to a standard implementation not optimized for energy, without penalizing the latency. In this dividing technique we compare the radix-8 divider is compared with one ...

this paper describes the design of a 2x2 micro strip patch antenna array in the frequency of 9.5ghz for radar applications, using substrate integrated waveguide, siw, for feeding network. the micro strip patches are aperture-coupled with the feeding network of siw. the feeding network consisting of a perpendicular coax-to-siw transition and two y-junction power dividers. the antenna is simulate...

In preparation for the 1997 SLC run, a novel RF bunchlength monitor has been installed in the SLC South Final Focus. The monitor consists of a ceramic gap in the beam pipe, a 160-ft long X-band waveguide (WR90), and a set of dividers, tapers and microwave detectors. Electromagnetic fields radiated through the ceramic gap excite modes in the nearby open-ended X-band waveguide, which transmits th...

A strong correlated equilibrium is a strategy pro le that is immune to joint deviations. Di erent notions of strong correlated equilibria were de ned in the literature. One major di erence among those de nitions is the stage in which coalitions can plan a joint deviation: before (ex-ante) or after (ex-post) the deviating players receive their part of the correlated pro le. In this paper we prov...

RÉSUMÉ. Cet article s’intéresse à la synthèse automatique d’agents en environnement incertain, se plaçant dans le cadre de l’apprentissage par renforcement, et plus précisément des processus de décision markoviens partiellement observables. Les agents (dénués de modèle de leur environnement et de mémoire à court terme) sont confrontés à de multiples motivations/objectifs simultanés, problématiq...

This paper will discuss the design and use of Optimal Ratio Combiners in modern telemetry applications. This will include basic design theory, operational setups, and various types of combiner configurations. The paper will discuss the advantages of predetection vs. post-detection combining. Finally, the paper will discuss modern design techniques.

This letter presents an eigenfilter approach to obtain the optimal weights of a diversity receiver using maximum ratio combining (MRC). It is shown that the optimal weights correspond to a matched filter solution for stochastic signals and that the optimal weights are the same regardless of the signal branch correlation.
