Phased Antenna Array Implementation with USRP [PDF]
2017 IEEE Globecom Workshops (GC Wkshps), 2017 This paper presents the implementation of a phased antenna array with Universal Software Radio Peripheral (USRP). The antenna elements of the array are driven by individual USRP platforms. Hence, the synchronization and calibration of different platforms are required in phase and amplitude.

Phase Calibration of Distributed Antenna Arrays
IEEE Communications Letters, 2023 Antenna arrays can be either reciprocity calibrated (R-calibrated), which facilitates reciprocity-based beamforming, or fully calibrated (F-calibrated), which additionally facilitates transmission and reception in specific physical directions. We first expose, to provide context, the fundamental principles of over-the-air R- and F-calibration of ...

A phased antenna array for surface plasmons [PDF]
Scientific Reports, 2016 AbstractSurface plasmon polaritons are electromagnetic waves that propagate tightly bound to metal surfaces. The concentration of the electromagnetic field at the surface as well as the short wavelength of surface plasmons enable sensitive detection methods and miniaturization of optics.
