Abstract
A meander embedding sector traveling-wave antenna for series superconducting detectors is provided, including: a detector array, a meander metal layer, a pair of bend-line metal layers, and a pair of sector metal layers. The detector array is individually connected in the meander metal layer and the pair of bend-line metal layers; the pair of bend-line metal layers is correspondingly connected to the pair of sector metal layers; and the pair of sector metal layers is disposed symmetrically centered on the detector array. The antenna improves working bandwidth of THz antenna and completes low-impedance matching between a single antenna and each series Josephson junction embedded in the antenna. The embedding meander can be connected to a plurality of low-impedance detectors, and performance of the antenna is not influenced while target impedance matching is completed. And the working bandwidth of the THz antenna embedded with the series detectors is increased.
