Abstract
We present a multi-chroic kinetic inductance detector (KID) pixel design integrated with a broadband hierarchical phased-array antenna. Each low-frequency pixel consists of four high-frequency pixels. Four passbands are designed from 125 to 365 GHz according to the atmospheric windows. The lumped element KIDs are designed with 100 nm Al as the inductor and with Nb parallel plate capacitors using hydrogenated amorphous Si as the dielectric. Due to the broadband coverage, two different types of structures are needed to couple light from microstrip lines to the KIDs. The KIDs designs are optimized for a 10-m-class telescope at a high, dry site.
