The paper describes a selective multi-element receiver of millimeter radiation based on the film structure of a metal-dielectric-temperature-sensitive layer with a pyramidal horn micro antenna, providing registration of continuous and pulsed millimeter radiation. In the absorbing layer of the receiver from chromium at the level of 0.5, the width of the resonance absorption bands is 16.5 and 16.3 GHz in the frequency bands 100 - 116.5 GHz and 206.7 - 223 GHz, respectively. The receiver is made in a miniature standard glass-to-metal package. Micro antenna fixed on a removable housing cover. The directional diagrams (DN) in the H and E planes are almost identical, the width of the main lobe of the DN at 0.7 is 14.8°. Calculated DN radiation horn microantenna in three-dimensional form. Combining the receiver with a pyramidal horn micro-antenna and optical-mechanical scanner allows you to create a two-dimensional picture of the object in the millimeter range at room temperature. The detecting ability of the receiver in the indicated frequency ranges is 5,48∙1011W−1•Hz1/2•cm, and the time constant is ~ 6.85•10−6s. The operational parameters of the receiver allow you to confidently record both constant and pulsed radiation in millimeter wavelengths. The developed receiver can be successfully operated both for civil and military purposes.
