Abstract
A novel and useful THz radiation detector comprising a suspended wideband planar skirt antenna for achieving low thermal mass and high electrical performance. The antenna comprises only the perimeter or “skirt” of the antenna. The antenna has multiple loops where each loop comprises a conductor that covers the perimeter or skirt and includes multiple inner and outer arms. The total length of each loop has a length substantially one wavelength. One or more ports or load impedances are connected at the center of the antenna and shared by one or more loops. A thermal sensor detects the heat generated in the load resister and converts the heat energy to an electrical signal which is transmitted to read out circuitry via signal lines that run together with a holding arm. The holding arm functions as both a path for the read out signals as well as providing mechanical support for and effectively suspending the antenna.
