Abstract

The invention provides an antenna. The antenna comprises an antenna radiation unit, a grounding unit and a feed unit, wherein the antenna radiation unit is provided with two linear grooves and a plurality of curved grooves, the two linear grooves are perpendicular to each other and penetrate through the antenna radiation unit, the antenna radiation unit is divided into four sub-antenna radiation units by the two linear grooves, and the plurality of curved grooves are distributed at the periphery of the antenna radiation unit at equal intervals and are used for dividing current lines generatedby the four sub-antenna radiation units. The beneficial effects of the invention are that the antenna radiation unit is provided with the two linear grooves and the plurality of curved grooves, thereby increasing the resonance path, and expanding the bandwidth of the antenna; and the current on the antenna radiation unit can be ensured to flow along the orthogonal direction, and the isolation degree between ports is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of communications, in particular to an antenna. 【Background technique】 [0002] With the arrival of the fifth-generation mobile communication technology, higher requirements are put forward for the broadband characteristics and isolation of base station antennas. MIMO antenna technology is the core technology of 5G (fifth generation mobile communication technology, 5th generation mobile networks) communication. The application of multiple antennas will lead to huge challenges in antenna isolation. The isolation between antenna ports will directly affect the reception of the system. Channel sensitivity and receiver stability. [0003] The methods for improving antenna isolation in existing antennas mainly include differential feeding or hybrid feeding; however, differential feeding increases the difficulty and complexity of antenna feeding network design, and the structure of hybrid feeding is asymmetric, ...
