We discuss the design and expected performance of STRIP (STRatospheric Italian Polarimeter), an array of coherent receivers designed to fly on board the LSPE (Large Scale Polarization Explorer) balloon experiment. The STRIP focal plane array comprises 49 elements in Q band and 7 elements in W-band using cryogenic HEMT low noise amplifiers and high performance waveguide components. In operation, the array will be cooled to 20 K and placed in the focal plane of a ~0.6 meter telescope providing an…

Comparison of the crossed and the Gregorian Mizuguchi-Dragone for wide-field millimeter-wave astronomy.
TLDR
This work compares the geometric and physical-optics performance of two configurations of offset dual-reflector antennas that obey the Mizuguchi-Dragone condition and concludes that the crossed configuration has a larger diffraction-limited field of view but within this limit both configurations have roughly the same instrumental polarization.
