This item was taken from the IEEE Conference ' Feed networks for antenna-array coupled TES bolometers for CMB polarimetry ' Measurements of the Cosmic Mirowave Background's (CMB) temperature have provided new insight into the origins of our universe, and these experimental successes have been driven by advancements in detector technology. The next generation of experiments have just started measuring the CMB's polarization with monolithic detector arrays that integrate an antenna and filtering on-chip with the detectors. Caltech and JPL are playing a leading role in this effort through their antenna-coupled TES-bolometers. Each pixel of a focal-plane imaging array contains an antenna that itself is an array of coherently driven slot-dipoles. We feed each polarization of this dual-polarized antenna with separate microstrip summing-trees that pass power through in-line band-defining filters before termination at the bolometers.
