Abstract

The invention provides a dual-broadband complementary antenna. The antenna comprises double-layer cross electromagnetic dipoles, a feed structure and a reflector; the double-layer cross electromagnetic dipoles and the feed structure are arranged in the reflector; the double-layer cross electromagnetic dipoles include a pair of double-layer electromagnetic dipoles which are arranged at two sides of the feed structure in an X-shaped symmetrical mode. The antenna has the advantages of wide impedance bandwidth, high stability, high gain, low cross polarization, high front-to-rear ratio, nearly symmetrical E and H surfaces, and the like. Therefore, the antenna is a competitive antenna which can be applied to 2G / 3G / LTE / WLAN base station communication and can satisfy the requirements for safety, directionality and high data transmission rate.

Description

technical field [0001] The invention relates to an antenna, in particular to a double broadband complementary antenna with a double-layer crossed electromagnetic dipole structure applied to 2G / 3G / LTE / WLAN communication. Background technique [0002] With the rapid development of modern wireless communication systems, multi-band and wide-band antennas with high gain are urgently needed for communication between base stations. Due to the prominent features of multi-band antennas, such as reducing the cost by reducing the number of antenna elements and miniaturizing the installation area of ​​base station antennas, many dual-band antennas with high performance have been proposed in recent years. Typically, however, these dual-band antennas will be omnidirectional and low gain. From the point of view of system design, the directional antenna should meet the requirements of safety and efficiency. In addition, these antennas usually have a narrow impedance bandwidth and cannot c...
