Abstract

The invention relates to a dipole antenna with an adjustable feeding frequency and a method for adjusting an index of the antenna. The dipole antenna comprises a feeding end coaxial line, a coupling end coaxial line and oscillator arms; an inner conductors of the feeding end coaxial line and the coupling end coaxial line are connected through a wire above the oscillator arms; upper parts of outer conductors of the feeding end coaxial line and the coupling end coaxial line are respectively connected with the oscillator arms at two sides; lower ends of the outer conductors are respectively connected to the ground; and the coupling end coaxial line extends to below a ground plane. The dipole antenna is simple in structure and is realized by using the coaxial lines to feed, and the height of the antenna is adjustable. A method for adjusting the index of the dipole antenna fed by a dipole adjusts the length of the coupling end coaxial line and adjusts a center frequency of antenna resonance, is very simple and convenient to operate, and realizes a multi-frequency multiplexing function of one antenna. A front-to-rear ratio of the antenna can be adjusted through adjustment of the length of the coupling end coaxial line and the height of the antenna; and the method has very high practical value in optimization of the front-to-rear ratio of the antenna and optimization of a cross polarization ratio of the antenna in a dual polarized antenna.
