Abstract :
We report on the development of antenna-coupled bolometers using Transition-Edge Sensors (TES) for millimeter waves. Our design uses a double-slot dipole antenna which feeds superconducting niobium microstrip. Microstrip filters are used to define the frequency band to which the bolometers are sensitive. The microstrip is terminated with a load resistor and the dissipated power is measured using a TES. We present the results of electrical and optical characterization of single bolometer pixels and discuss the development of a large bolometer array based on this design. This array is being developed for a Cosmic Microwave Background (CMB) polarization anisotropy experiment.
