Multi-band elementary radiating cell

Abstract

A radiating device operating in two distinct frequency bands, a high frequency band and at least one sub-band of a low frequency band, the device comprises: at least one element of patch type adapted to the high frequency band and linked to a first feed, at least one element of folded slot type, adapted to the low frequency band and linked to a second feed different from the first feed, a filter positioned between the element of patch type and the first feed, configured to filter the sub-band of the low frequency band and to be passing for the high frequency band, and wherein the elements of which it consists are positioned in a surface area of less than or equal to a square of edge λ/2, where λ is the wavelength corresponding to the maximum frequency of the high frequency band.
