System and cost analyses of broad-band fiber loop architectures
IEEE Journal on Selected Areas in Communications, 1990Analyses of four broadband fiber-optic subscriber loop architectures, including active (high-speed time division multiplexing (TDM)-based) and passive (dense wavelength division multiplexing (WDM)-based, WDM-based with an analog subcarrier-multiplexing overlay, and splitter-based) double-star topologies, are presented.

A compact slot loop rectenna for dual-band operation at 2.4- and 5.8-GHz bands
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016A compact dual-band square slot loop rectenna fed by a microstrip line (MSL) for 2.4- and 5.8-GHz bands is presented. Instead of exploiting resonances of integer multiples of full wavelength in conventional dual- or multi-band slot loop antenna design, it is for the first time that the half-wavelength and one-wavelength resonant modes of MSL-fed slot ...

A low-cost, dual-band RF loop antenna and energy harvester
2017 IEEE Topical Conference on Wireless Sensors and Sensor Networks (WiSNet), 2017This paper presents the design of a Dickson charge pump circuit paired with a compact, multi-resonant loop antenna for RF energy harvesting at 900 MHz and 2.4 GHz. It enables the RF harvester to operate efficiently both indoors and outdoors. A prototype design using surface mount components is simulated using ADS. It achieves a sensitivity of −21.2 dBm

Design, simulation and measurement of loop plasma antenna in UHF band
2016 24th Telecommunications Forum (TELFOR), 2016Plasma antenna is a modern and performance technology that is designed and fabricated as appropriate replacement for current antenna. A new Plasma loop antenna based on DC discharge ionized is proposed in this paper. The diameter of the ring discharge tube of the antenna is 12 inch and the dimension of commercial fluorescent for simulation and ...

Integrated S-Band transmitter with on-chip DC-DC converter and control loop
2012 IEEE Radio Frequency Integrated Circuits Symposium, 2012A highly integrated high-power transmitter has been designed in a high breakdown GaAs MMIC technology. The transmitter includes, on top of an S-Band 10 W class-F HPA, a DC/DC converter and its associated gate driver, the full voltage regulation control loop, which provides a significant step for phased array transmit chain miniaturization and transmit ...

PLL Frequency Synthesizers: Phase Noise Issues and Wide Band Loops
2000New DVB standards impose very tight requirements for phase deviation in frontend tuners. Combining these requirements with higher integration levels are the challenges of current mixer-oscillator and PLL circuits, where behavioural models are essential to understand and guide the design work. Linear loop models and algorithms for filter calculation are
