Embodiment Construction

[0028] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] The Tiantong satellite ground station self-adaptive active antenna provided by the present invention, such as figure 1 As shown, it includes a passive antenna ANT, a first duplexer DPX1, a second duplexer DPX2, a low noise amplifier LNA, and three gain amplifiers are gain amplifier AMP1, gain amplifier AMP2, gain amplifier AMP3, and the second Duplexer DPX2, adaptive module and power amplifier PA;

[0030] The passive antenna ANT is used to receive wireless signals into the air and transmit wireless signals, and its function is to receive and send wireless signals. The passive antenna itself is an antenna without any active components. In practical applications, it is an ordinary antenna with some common metal bodies. It is not limited in the present invention, and the commonly used passive antenna is selected. Can.

Abstract

The invention provides a Tongtong satellite ground station self-adaptive active antenna and an adjusting method thereof. The active antenna comprises a passive antenna ANT, a first duplexer, a low-noise amplifier, a self-adaptive module and a power amplifier. The passive antenna ANT is used for receiving and transmitting wireless signals to the air; the self-adaptive module comprises a wireless signal input end, a signal control end and a signal transmitting end, the wireless signal input end receives signals from the low-noise amplifier, and the signal control end adjusts attenuation values of the signals in a self-adaptive mode by monitoring the size of the wireless input signals so as to control enabling of the power amplifier. According to the technical scheme of the active antenna andthe self-adaptive adjustment method thereof provided by the invention, the cost of a passive antenna and a 10-meter or 50-meter cable is saved, the use difficulty is reduced, and the amplitude of a receiving and transmitting signal can be automatically adjusted to the safest and optimal communication state.

Description

technical field [0001] The invention belongs to the technical field of radio transmission, and relates to an adaptive active antenna of a Tiantong satellite ground station and an adjustment method thereof. Background technique [0002] Active antennas are antennas in which a larger antenna array is formed from a large number of antenna elements. Some radio transceivers are directly connected to these antenna elements, and these radio transceivers act like a single transceiver connected to a similarly sized antenna array. The purpose of this arrangement is to obtain the desired radiation pattern (radio beam), equivalent non-directional radiated power (EIRP) and sensitivity. However, such antenna arrays can only provide satisfactory functionality if the power (amplitude) and phase of the emitted radio waves are known and controllable. [0003] With the development of mobile communication technology to 4G (fourth generation mobile communication technology), the coverage area ...
