AERIAL SYSTEM Russian patent published in 1994 - IPC

FIELD: aerial equipment. SUBSTANCE: for increase of isolation between receiving and transmitting aerials of repeater each aerial is built in the form of array composed of pair of radiators of linear polarization mounted one above other on common support. In each pair radiators may be excited in phase or in antiphase. In case of in phase excitation radiators may be spaced by λ/2 in plane E in symmetry with respect to center of array and in case of antiphase excitation they are spaced by λ/2 in plane H. EFFECT: improved operational characteristics. 4 dwg
