Abstract

The invention discloses a low-profile high-gain fractal small-scale base station antenna, which is characterized in that it includes a radome, a reflector assembly, a substrate substrate, a metal partition array, a dielectric substrate printed with an antenna vibrator, and an antenna vibrator. The feeding coaxial feeder; the antenna vibrator includes four sheet-shaped units that are symmetrical about left and right, up and down, two units on each opposite corner of the four-sheet units form a pair of dipoles, and the four sheet-shaped units form a cross oscillator; Iterative I2 square von Koch fractal curves are connected head to tail to construct a Minkowski fractal ring, and then filled as a plane piece, and a pair of diagonals are constructed at the upper right corner or upper left corner of the fractal ring with the diagonal as the axis of symmetry Ears, formed by merging them with fractal rings. Through the reasonable design of the antenna structure of the fractal small base station, the present invention realizes significant suppression of low profile back lobe, significant improvement of front-to-back ratio and cross polarization ratio; realizes high gain and high efficiency that cannot be achieved by a pair of conventional cross oscillators.

Description

technical field [0001] The invention relates to the technical field of cellular mobile communication base station antenna equipment, in particular to a low-profile high-gain fractal small base station antenna. Background technique [0002] The base station antenna is the air interface connecting the user and the network in the cellular mobile communication system, so it is one of the most critical components of the entire system, and its performance directly determines the communication quality. At present, base station antennas are divided into two categories according to the application occasions; one is outdoor large-scale macro base station antennas, which are characterized by wide frequency bandwidth, large number of array elements, high gain, precise beam forming, and large power capacity, suitable for large-scale, user Sparse occasion coverage; the other type is small base station antennas, which are characterized by narrow frequency bands, fewer array elements, lower...
