چکیده
v) A novel beam-steering leaky-wave antenna that uses reactive loading capacitors along the leaky line is presented. The reactive loading varies the phase constant of the leaky line, altering direction of the main beam. A prototype was constructed and tested, demonstrating that a beam scanning angle of 23” is obtained by periodically loading the 0.06527 pF capacitors along the leaky line at 4 GHz. An electronic beam-steering antenna of scanning angle 13” was established by replacing the MIM capacitors with varactors.

Wideband plasmonic beam steering in metal gratings.
We demonstrate controllable light deflection in thick metal gratings with periodic subwavelength slits filled with an active material. Under specific illumination conditions, the grating becomes nearly transparent and acts as a uniform optical phased-array antenna where the phase of the radiating elements is controlled by modifying the index of refraction of the material that fills each slit. T...

Metasurfaces offer significant potential to control far-field light propagation through the engineering of the amplitude, polarization, and phase at an interface. We report here the phase modulation of an electronically reconfigurable metasurface and demonstrate its utility for mid-infrared beam steering. Using a gate-tunable graphene-gold resonator geometry, we demonstrate highly tunable refle...

On bi-static or multi-static space-borne radar the appropriate digital beam-former (DBF) algorithms can obtain multi-angular synthetic aperture radar (SAR) data and enhance signal-tonoise ratio. Some applications ask for short revisit time that need to ensure seamless coverage to obtain a wide swath SAR image data with a single satellite using digital beam-forming on receive scheme [1]. The tra...
متن کاملDigitally Excited Reconfigurable Linear Antenna Array Using Swarm Optimization Algorithms
This paper describes the synthesis of digitally excited pencil/flat top dual beams simultaneously in a linear antenna array constructed of isotropic elements. The objective is to generate a pencil/flat top beam pair using the excitations generated by the evolutionary algorithms. Both the beams share common variable discrete amplitude excitations and differ in variable discrete phase excitations...
