Problems solved by technology

Therefore, it is difficult to use this design concept to make the antenna bandwidth cover all 2G / 3G / 4G operating frequencies as low as 700MHz and as high as 2620MHz
To achieve this matching purpose, the internal matching circuit structure of the adjustable capacitor module 460 is also a design problem

Abstract

An active antenna system with multiple feed ports and a control method of the active antenna system are provided. The active antenna system includes an antenna radiation element, a first feed port and a second feed port. If the first control circuit is in a close state, the first feed port and a first physical position of the antenna radiation element are connected with each other, so that a signal is fed to the antenna radiation element through the first feed port and the first physical position. If the second control circuit is in the close state, the second feed port and a second physical position of the antenna radiation element are connected with each other, so that the signal is fed to the antenna radiation element through the second feed port and the second physical position.

Description

technical field [0001] The present invention relates to an antenna system and its control method, and in particular to an active antenna system with multiple antenna feeding ports and its related control method. Background technique [0002] Generally speaking, the antennas used in consumer wireless products are usually single-fed passive antennas (Single-Fed Passive Antenna), which are usually simple in structure, simple in application, cheap, small in size, and single The antenna only needs a single antenna feed port, and can support all frequency bands required by the system at the same time, such as: Bluetooth (Bluetooth) antenna, wireless network WiFi antenna, and second generation (2G) / third generation (3G) mobile communication Mobile phone antenna. Among them, the second-generation mobile communication frequency bands are about 824MHz-960MHz and 1710MHz-1990MHz, while the third-generation mobile communication frequency bands usually pay special attention to the Ban...
