Abstract

The invention discloses an efficient transmitting-receiving antenna array device. The efficient transmitting-receiving antenna array device is composed of an antenna traction plate (100) and an antenna feed plate (200); the antenna traction plate (100) is placed above the antenna feed plate (200) at a vertical interval and is a single-layer PCB, and eight coupling units (110) are evenly arranged on the surface of the antenna traction plate (100) and are rectangular metal; the antenna feed plate (200) is a double-layer PCB, a lower layer of the antenna feed plate (200) is a metal ground layer (210), an upper layer of the antenna feed plate (200) is a feed layer (220), and the feed layer (220) comprises a feed network and eight evenly-arranged rectangular radiating elements (230) connected with the feed network. According to the efficient transmitting-receiving antenna array device, the feed network in the feed layer (220) feeds the eight radiating elements (230) so that efficient radiation of two cross polarizations can be achieved; the efficient transmitting-receiving antenna array device can be applied to various frequency bands for wireless communication. According to the technical scheme, the high frequency width is achieved, and meanwhile the efficient transmitting-receiving antenna array device has the advantages of being small in size, simple in structure and high in gain.

Description

technical field [0001] The present invention relates to a 4G antenna, and more specifically, to a MIMO (Multiple Input Output) antenna, a key technology of 4G. Background technique [0002] With the development of mobile communication technology to the third generation (3G), especially the emergence of smart terminals, the market's demand for mobile data has rapidly expanded. The current 3G technology is originally developed based on voice communication. Due to the impact of mobile data Bandwidth limitation, for mobile data, can no longer meet the rapid development of mobile data demand. MIMO (multiple input and output) multi-antenna technology is a key technology in 4G, which can greatly increase the capacity of wireless communication systems and effectively improve the performance of wireless communication systems, which is very suitable for the requirements of high-speed data in future mobile communication systems . MIMO (multiple input and output) multi-antenna technol...
