Problems solved by technology

We know that if the output power of an RF transmitter is doubled while maintaining linearity, its cost will increase by 0.8 to 1 times, and its DC power consumption will increase by 1 to 1.2 times.

Abstract

The invention discloses a remotely controlled two-dimensional plane phase control active integrated antenna. The antenna comprises an optical module, an intermediate frequency transceiver module and antenna units. The optical module connected with a near-end machine is connected with a plurality of radio frequency transceiver modules through the intermediate frequency transceiver module and an intermediate frequency power splitter / combiner, and each radio frequency transceiver module is connected with an antenna unit. The antenna provided by the invention is different from a conventional array antenna in that in an active integrated antenna array in the invention, each antenna unit is directly connected with a complete radio frequency transceiver module, the signal of each unit finishes power splitting / combining over an intermediate frequency and is connected with the optical module after passing through the intermediate frequency transceiver module, and at last intermediate frequency signals can be converted into optical signals through the optical module for long-distance low-loss transmission; and the phase of the radio frequency transceiver module after each antenna unit can be remotely controlled so that the orientation of the wave beam of a whole array in the horizontal direction and vertical direction can be configured and scanned and the radiation intensity and coverage can be adjusted.

Description

technical field [0001] The invention relates to the field of active antennas, in particular to a two-dimensional planar phase-controlled active integrated antenna that can be remotely controlled. Background technique [0002] Antennas are one of the key components of various wireless communication systems. The main technical indicators to measure their pros and cons are: impedance bandwidth, beam width, sidelobe level, gain and efficiency, etc. The conductor loss, dielectric loss of the antenna radiating unit, the insertion loss of the feeding network and the loss of the feeder will greatly reduce the efficiency of the entire system, resulting in a considerable proportion of the transmitter power being dissipated by the antenna and the feeder, and seriously affecting the receiving sensitivity. Therefore, high efficiency and intelligence have become the research goals of the next generation of wireless communication antennas. [0003] A traditional cellular mobile communicat...
