FIELD: physics, radio. ^ SUBSTANCE: invention is related to the field of radio engineering, namely, to corner antennas, also to antenna arrays for cellular communication systems, which are intended both for transmission and reception of radio signals. Antenna includes row of radiators, reflector, power supply circuit with two high-frequency sockets and summator-dividers and divisors and radiolucent covering. Every pair of radiators is made in the form of circuit board with two orthogonally installed printed radiators in the form of "Maltese cross". Halves of "Maltese cross" are connected to each other, have zero resistance to DC. Every circuit board is fixed to reflector by two stakes and two external braids of coaxial cable. Two radiators are connected crosswise by links to supply cables. Pairs of crosswise connected radiators are installed along longitudinal axis of antenna to create antenna array. In antenna technical solutions are used that increase uncoupling value between channels. Arrangement of radiators makes it possible to use technology of printed circuit boards in their manufacturing, which simplifies process of corner antenna serial production. ^ EFFECT: creation of corner antenna with double polarisation of 45 degrees, with required shape of directional pattern, high level of uncoupling between channels and low level of VSWR in range of frequencies. ^ 5 cl, 6 dwg |
