The paper presents an implementation and tests of a simple home entertainment distribution architecture (server + multiple clients) implemented using two conventional cabling architectures: CATV coaxial cable and conventional Ethernet. This architecture is created taking into account the “Home gateway” concept present in most attempts to solve the problem of the “Intelligent home”. A short pres...

The present paper describes a capacitive feed (C-feed) for small, low-profile linear antennas. A meander line, which is the radiating element, in such antennas with a metallic back conductor electromagnetically couples a metallic feed plate placed between the meander line and the back metal (ground). This antenna has a very small leakage current on the outer surface of the coaxial cable and can...

We investigated the influence of using a conical end on the longitudinal electrical nearfield generated by a coaxial cable. Simulations with Finite Integration Technique show that this influence greatly varies along the longitudinal axis. Experimental measurements were also carried out. To that purpose, we designed a new set-up to measure the electrical field in one direction with a spatial res...

This report presents a brief review as well as some theoretical background on radon (^Rn) emanation methods from solid samples. This is followed by a description of an experimental apparatus built at the Elliot Lake Laboratory. (Mining Research Laboratory. CANMET, E.M.R.) to measure the ^Rn emanation rate from ^Ra-bearing solid materials by the vacuum emanation method. Experimental data are pre...

Using MMICs in phased-array applications above 20 GHz requires complex RF and control signal distribution systems. Conventional waveguide, coaxial cable, and microstrip methods are undesirable due to their high weight, high l o s s , limited mechanical flexibility and large volume. bution in MMIC phased array antennas, is optical fiber. Presented are potential system architectures and their ass...

This paper presents a new method to improve the GBW (gain-bandwidth product) on negative feedback amplifiers. The proposed method is based on the introduction of time delay elements in the feedback loop, which can be exploited to retrieve significant bandwidth enhancements. This delayed feedback concept is analyzed, and considerations are presented for first order amplifiers, based on theoretic...

The creation of a quantum network requires the distribution of coherent information across macroscopic distances. We demonstrate the entanglement of two superconducting qubits, separated by more than a meter of coaxial cable, by designing a joint measurement that probabilistically projects onto an entangled state. By using a continuous measurement scheme, we are further able to observe single q...
