Geometric Phase in Phasing of Antenna Arrays [PDF]
Symposium - International Astronomical Union, 2002 The response of a pair of differently polarized antennas is determined by their polarization states and a phase between them which has a geometric part which becomes discontinuous at singular points in the parameter space. Some consequences are described.

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.
