PRINTED ANTENNA

摘要

The invention relates to the field of radio technology, more specifically to ultra-wideband antennae in the SHF range. The technical result is the production of an ultra-wideband printed antenna with low cross-polarization and low side lobes. The printed antenna comprises a section of an antipodal slotline, situated on a dielectric substrate, a section of a signal stripline, identical metal signal and ground plates, a section of an additional antipodal slotline, and first and second metal plates identical to the metal signal and ground plates respectively, the first metal plate being situated on the same plane of the dielectric substrate in the aperture region as the metal signal plate, and the second metal plate being situated on the same plane of the dielectric substrate in the aperture region as the metal ground plate. The section of the additional antipodal slotline without overlap does not have a zero overlap region, and, in the aperture region, the first metal plate is conductively coupled by metal connecting strips to the metal ground plate, and the second metal plate is conductively coupled by metal connecting strips to the metal signal plate.
