Abstract
Silicon platelet corrugated feedhorn for cosmic microwave background (CMB) measurements in the mm wave (130 to 170 GHz) have been developed for deployment for the polarization sensitive upgrade to both the Atacama Cosmology Telescope (ACTpol) and the South Pole Telescope (SPTpol). We present fabrication developments and the first results of a prototype monolithic feedhorn array consisting of 84 horns. Measurements show good beam quality across the needed bandwidth, return loss of -24 dB, an insertion loss of -0.4 dB, and cross polarization ofCitation
