Abstract

The invention relates to a dual polarization antenna radiation unit with function of coupled feeding, which comprises a body structure, a feeding device and a lead device; the body structure is an integrated structure composed of vibration arms (8), baluns(10) and a base (11); four vibration arms (8) and four baluns (10) are provided; one end of each of the four baluns (10) are uniformly arranged on the four sides of the base (11), while the other end is connected with the vibration arms (8) to form an inverted ''L''-shaped structure, and the four baluns (10) form a cavity structure; the free ends of the vibration arms (8) are all arranged back on to the cavity; and the feeding device is disposed in the cavity structure. The dual polarization antenna radiation unit with function of coupled feeding is simple structure, and convenient to mount, along with good signal isolation.

Description

(1) Technical field [0001] The invention relates to an antenna radiating unit, in particular to a dual-polarized antenna radiating unit adopting a coupling feeding mode. (2) Background technology [0002] Base station antennas are generally combined into an array of radiating elements of the same type to obtain high gain. At present, there are two main types of radiating units of base station antennas, which are air microstrip and symmetrical oscillator; however, in use, it is found that the connection structure between these two types of radiators and baluns is complicated, the installation is cumbersome, and the radiator and feeder The signal isolation between structures is poor, which affects the receiving and transmitting effect. (3) Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a dual-polarized antenna radiation unit with simple structure, convenient installation and good signal isolation for...
