Abstract

The invention discloses a time division-long term evolution (TD-LTE) dual-polarization radiation unit, which comprises symmetrical vibrator radiation arms, feed baluns and supporting arms, wherein the number of the symmetrical vibrator radiation arms is two pairs, and the two pairs of symmetrical vibrator radiation arms are distributed across; each pair of symmetrical vibrator radiation arms is fixed on a floor through the supporting arms respectively; and the number of the feed baluns is 2, one end of each feed balun is connected with one of the corresponding symmetrical vibrator radiation arm, and the other end of the feed balun is fixed at the bottom of the supporting arm of the other one of the corresponding symmetrical vibrator radiation arm. Because two pairs of symmetrical vibrators form an integrated structure, the dual-polarization radiation unit has electric properties such as high gain, wide working bandwidth, high isolation degree, low cross polarization level and the like.

Description

technical field [0001] The invention relates to an antenna radiation unit, in particular to a broadband dual-polarization radiation unit of a TD-LTE smart antenna. Background technique [0002] In recent years, mobile communication has developed rapidly. In order to better meet user needs, operators need to provide better and faster 3G broadband services. Therefore, the existing TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) intelligent technology has evolved to TD-LTE (TD-SCDMA Long Term Evolution, TD-SCDMA Long Term Evolution) intelligent technology; in order to meet the needs of operators, we need to expand the working bandwidth of the antenna. The working frequency band of the existing TD-SCDMA smart antenna is 1880-1920MHz and 2010-2025MHz dual-band, while the working frequency band of TD-LTE smart antenna has been extended to 1880-1920MHz, 2010-2025MHz and 2570-2620MHz three-band, the existing...
