Antenna-coupled TES bolometers used in BICEP2, Keck array, and SPIDER

, 2015
We have developed antenna-coupled transition-edge sensor (TES) bolometers for a wide range of cosmic microwave background (CMB) polarimetry experiments, including BICEP2, Keck Array, and the balloon borne SPIDER. These detectors have reached maturity and

Mutual Coupling Reduction between Patch Antennas Using Meander Line

International Journal of Antennas and Propagation, 2018
Meander lines (MLs) in two configurations are presented to reduce the mutual coupling (MC) between two microstrip patch antenna elements. Inserting a slot in the ground plane between the antenna elements is a simple method to reduce the MC, while adding ...
