Abstract

The invention discloses a broadband dual-polarization antenna with gradually-changing open groove type radiation units. The broadband dual-polarization antenna comprises a metal floor, four reflection plates arranged around the metal floor in an inclined mode and the four radiation units erected on the metal floor. A square box-shaped structure is defined by the four radiation units in the center of the metal floor. A gradually-changing open groove is formed in the portion, from the center of the bottom to the top, of the front face of each radiation unit. The broadband dual-polarization antenna is provided with the four radiation units defining the square box-shaped structure, and therefore compared with a one-unit antenna, good gains are achieved; each radiation unit is provided with the corresponding gradually-changing open groove, and therefore impedance matching can be achieved, and the bandwidth can be broadened; the radiation characteristics of the radiation units can be changed as well, and therefore the antenna can have the directing property, and energy can be perpendicularly radiated out through the antenna; the broadband dual-polarization antenna has the advantages of being simple in structure, low in cost, small in size and wide in bandwidth, and is suitable for engineering application.

Description

technical field [0001] The invention relates to a broadband dual-polarization antenna, in particular to a broadband dual-polarization antenna with a gradually changing slotted radiation unit, belonging to the field of wireless communication. Background technique [0002] With the rapid development of wireless communication technology, all kinds of electronic equipment are developing towards miniaturization and broadband, and as a bridge and air interface of wireless communication technology, it is bound to develop in this direction. The traditional antenna is composed of a fixed element, which has poor shielding, low integration, large size, and narrow frequency band. These factors make the traditional antenna unable to meet the needs of future wireless communication. Therefore, research on small broadband antennas has become an important topic. [0003] With the development of broadband communication network technology, especially the key step of LTE technology 3G to 4G, L...
