The utility model discloses a low-cost
base station antenna structure. The low-cost
base station antenna structure comprises a reflecting plate and a plurality of oscillators, the reflecting plate comprises a base plate, a plurality of isolation plates and a plurality of side baffles, the isolation plates are arranged in the middle of one side of the base plate and are integrally formed by
punching the base plate, and the side baffles are arranged on the side edge of one side of the base plate and are integrally formed by bending the base plate; the oscillator comprises a
radiation plate and a
balun plate, one end of the
balun plate is connected with the
radiation plate, and the other end of the
balun plate is connected with one side of the substrate; according to the above structure, on the premise that the appearance and the strength of the whole
machine are not affected, the isolation plate, the side baffle plate and the substrate are integrally formed to form the integrated reflection plate, plastic rivets are not needed for fastening, manual
assembly is not needed, the material cost is relatively reduced, automatic
assembly is easy to achieve, and the
layout flexibility of the whole
machine is improved. And meanwhile, the antenna oscillator is changed into the single-balun oscillator, so that the cost and the weight of the antenna can be effectively reduced, and the practicability is very good.
