The invention discloses a dual-frequency small-plate antenna. The dual-frequency small-plate antenna comprises a radio frequency connector, a coaxial cable, a reflector and a radome. A high-frequencydouble-sided copper-clad PCB is fixedly mounted on the reflector, the front surface of the high-frequency double-sided copper-clad PCB is provided with a first dual-frequency radiation vibrator, an impedance matching device, a feed connection point and a front transmission line, and the back surface of the high-frequency double-sided copper-clad PCB is provided with a second dual-frequency radiation vibrator, a balanced and unbalance converter unit, a grounding welding position and a front transmission circuit; the front transmission circuit comprises a first impedance transformation circuit segment, a second impedance transformation circuit segment and a third impedance transformation circuit segment; and the balanced and unbalance converter unit comprises a first balanced and unbalance converter, a second balanced and unbalance converter, a third balanced and unbalance converter, a fourth balanced and unbalance converter and a fifth balanced and unbalance converter. The dual-frequency small-plate antenna is small in size, light in weight and wide in frequency band, can perform dual-frequency covering, and good in radiation performance index.
Description
technical field [0001] The invention relates to the field of antennas, in particular to a dual-frequency small plate antenna. Background technique [0002] Most of the existing dual-frequency small plate antennas of the wireless local area network use two antennas of different frequencies to be installed in one antenna shell. Interference between antennas is easy to occur, and the effect of the product is poor; a small number of dual-frequency small plate antennas cannot meet the needs of wireless LAN terminal equipment due to their failure to solve the problems of low standing waves and good directivity. in the application. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dual-band small plate antenna with small volume, light weight, wide frequency band, dual-band coverage, and better radiation performance index in view of the above-mentioned defects of the prior art. [0004] The technical solution adopted b...
