FIELD: radio engineering including antenna engineering.
SUBSTANCE: proposed antenna array that can be used in antenna communication and radar facilities for electrical scanning primarily in superhigh and extremely-high frequency bands has waveguide radiators with nonoverlapping apertures of high- and low-frequency bands disposed in one aperture and affording frequency-selective isolation between apertures of high- and low-frequency bands. Novelty in antenna array is use of low-frequency band radiators made in the form of diaphragmatic periodic waveguides provided with cutoff band for waves propagating in operating frequency band of high-frequency band radiators.
EFFECT: simplified design, extended frequency band affording frequency-selective isolation between apertures.
