Uniform circular arrays for phased array antenna

open access: yes2011 Loughborough Antennas & Propagation Conference, 2011
This paper compares the performances of a number of uniform circular array (UCA) configurations for phased array antennas. A UCA geometry is targeted due to its symmetrical configuration which enables the phased array antenna to scan azimuthally with minimal changes in its beam width and sidelobe levels.

Infrared Phased-Array Antenna

open access: greenMicrowave and Optical Technology Letters, 2008
AbstractPhased addition of currents from multiple dipole antennas is demonstrated for the first time at a wavelength of 10.6 μm. Coplanar strip lines are used to interconnect the antennas, preserving the phase of the individual infrared‐frequency currents, which are summed together at a common bolometric load.
