Design guidelines for a terahertz silicon micro-lens antenna
Alonso del Pino, María; Llombart, Núria; Chattopadhyay, G.; Lee, Craig; Jung Kubiak, Cecile; Jofre Roca, Lluís; Mehdi, Imran (2013-01-15)
Article
Accés restringit per política de l'editorialA silicon lens antenna suited for future integrated terahertz arrays has been proposed recently. The antenna consists of an extended hemispherical silicon lens fed by a leaky-wave waveguide feed. The primary advantage is ... -
Silicon micro-lens antennas for THz integrated arrays
Alonso del Pino, María; Llombart, Nuria; Lee, Clement; Jung, C.; Chattopadhyay, G.; Jofre Roca, Lluís; Mehdi, Imran (IEEE, 2011)
Article
Accés restringit per política de l'editorialIn this paper, we describe the characterization of silicon micro-lenses fabricated by two different techniques, one using laser micromachining and the other developed using photolithographical techniques. The micro-lens ... -
Silicon microlens antenna for multi-pixel THz heterodyne detector arrays
Lee, Choonsup; Chattopadhyay, Goutam; Jung, Cecile; Reck, Theodore; Cooper, Ken; Peralta, Alex; Lin, Robert; Mehdi, Imran; Alonso del Pino, María; Llombart Juan, Nuria (Institute of Electrical and Electronics Engineers (IEEE), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialSilicon micromachined RF passive components such as washers, waveguide with 90 degree bends for 325-500 GHz band, and silicon-stacked blocks for W-band (75-110 GHz) GaAs power amplifiers have been designed, microfabricated, ... -
Silicon micromachined lens antenna for THz integrated heterodyne arrays
Llombart Juan, Nuria; Lee, Choonsup; Alonso del Pino, María; Chattopadhyay, Goutam; Jung Kubiak, Cecile; Jofre Roca, Lluís; Mehdi, Imran (Institute of Electrical and Electronics Engineers (IEEE), 2013-09)
Article
Accés restringit per política de l'editorialIn this paper, we present the design, fabrication, and measurements of a lens THz antenna that can be fabricated using conventional photolithography and deep reactive etching processes. The antenna is composed of an extended ... -
Terahertz antennas with silicon micromachined front-end
Chattopadhyay, Goutam; Reck, Theodore; Jung Kubiak, Cecile; Lee, Choonsup; Siles, Jose Vicente; Chahat, Naser; Cooper, Ken; Schlecht, Erich T.; Alonso del Pino, María; Mehdi, Imran (Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialIncreasingly, terahertz systems are being used for multi-pixel receivers for different applications from mapping the star-forming regions of galaxies to stand-off radar imaging. Since microstrip patch antennas are too lossy ...
