Array of multichroic double-slot antennas with cold-electron bolometers for the 220/240 GHz channels of the LSPE Instrument
Paper in proceedings, 2019

The present paper tells about developing narrowband antennas for frequencies 220 and 240 GHz, which will be used in the LSPE balloon telescope to estimate foreground cosmic dust. For thisgoal, we used double-slot antenna with coplanar lines and Cold-Electron bolometers. The simulations show that we have achieved 5% bandwidth for 220 GHz and 5.5% bandwidth for 240 GHz for the single cell. There are also results for an array of unit cells using double-slot antennas and coplanar lines with CEBs. Besides that, the paper addresses the question of the use of SQUID readout for cold-electron bolometers.
