Abstract
This bolometric detector for electromagnetic radiation comprises: a receiving antenna (1) intended for collecting electromagnetic radiation and thus ensuring electromagnetic coupling; a resistive load capable of converting the electromagnetic power collected into heating capacity; a thermometric element (4) connected to the receiving antenna (1) via the resistive load and thermally isolated from a support substrate (2), capable of accommodating an electronic circuit that includes means of electric excitation (stimuli) and means of pre-processing the electric signals generated by said detector. The receiving antenna (1) is itself isolated from the support substrate (2).
