This paper shows that implementing a system for the reception and detection of submillimeter radiation on the basis of open planar microresonance structures in the form of apodized dielectric gratings with a fill factor that varies according to a linear law, connected through an impedance transformer with a low-barrier zero-bias Schottky detector diode, makes it possible to achieve• losses to reflection of −26.5 dB,• a standing-wave factor of 1.1,• conversion efficiency 98.6%, with an NEP of 8.05×10−12WHz−1/2.
