ULTRABROADBAND RADIATOR FOR PHASED ANTENNA ARRAY OF 8,5-12,5 GHz FREQUENCY RANGE Russian patent published in 2012 - IPC H01Q1/38 

FIELD: radio engineering.

SUBSTANCE: radiator for a phased antenna array has a line of at least two radiating elements, every of which comprises two dielectric plates, which are metallised at both sides and contact with each other by some of their sides, on each other metallised side of dielectric plates located outside the radiator's body, there is at least one radiating slot provided, on contacting metallised sides of dielectric plates there are the following components arranged: a power divider installed on the symmetrical strip line with a matching device and at least one excitation circuit of at least one radiating slot, which electrically via the matching device and the symmetrical strip line of the power divider is connected to at least one radiating slot.

EFFECT: expanded functional capabilities of the device due to provision of the possibility of wide-range tuning of its working frequency.
