Smart antenna

Abstract

The intelligence type antenna is an antenna array composed of two antenna units and T type connector. Two radio frequency switchers are setup between one antenna unit and T type connector. There are two transmission lines between two radio frequency switchers. After two radio frequency switchers are switched, through first transmission line or second transmission line, the antenna units connected to the radio frequency switcher are connected to the T type connector so as to make information fed to the two antenna units generate difference between in-phase or out-of-phase. Thus, two antenna units are utilized at same time. Comparing with traditional antenna diversity multitasking, the invention solves disadvantages that only one antenna is utilized at same time. The invention can receive information in optimal quality.

Description

technical field [0001] The present invention relates to a smart antenna, especially to an antenna array that uses a T-shaped connector to form two antenna units, and a two-radio frequency switcher is arranged between one of the antennas and the T-shaped connector, and the two radio-frequency switches Two transmission lines are arranged between the devices, so that the two antenna units are used at the same time, and the best quality information can be received. Background technique [0002] Due to the current wireless local area network (WLAN) specifications, in order to prevent dead ends in the use of wireless transceiver devices, it is required that the wireless transceiver device must have multiple antennas (Antenna Diversity), and the antennas will use antenna diversity to multitask (Antenna Diversity) technology, in order to achieve the best quality of information transmission and reception. [0003] When designing wireless transceivers in the industry, there has been ...
