ULTRA-WIDEBAND ANTENNA ARRAY

摘要

FIELD: radio engineering, communication.SUBSTANCE: ultra-wideband antenna array is formed by two electrically identical dielectric bases with metal coated layers in which there is a radiating aperture formed from flat horn radiators placed in several levels. The dielectric bases are built into each other along the direction of radiation such that an orthogonal structure is formed. Each dielectric base is excited with phase shift of 90° to obtain elliptical polarisation of right/left rotation.EFFECT: design of an ultra-wideband antenna array with any beam shape and with any type of polarisation and even with several types of polarisation at the same time.4 dwg
