Problems solved by technology

At the same time, active phased array antennas have a large number of T / R components, and the heat dissipation of these T / R components requires a large space, but the existing phased array antennas have a small element spacing, which is reserved for T / R components to dissipate heat The space is very small, making it difficult for T / R components to dissipate heat
In addition, in active phased array antennas, the existing couplers generally have poor isolation. When doing T / R component detection, interference from the outside world will affect the detection effect

Abstract

The invention relates to an active phased array antenna. The active phased array antenna comprises an antenna array and N T / R components. Each T / R component is connected with a corresponding one of the microstrip antennas through a microstrip line. Wherein a portion of each of the microstrip lines positioned between the corresponding microstrip antenna and the T / R component is bent at a predetermined angle to form a bent section of a first predetermined length, and the bending directions of the bending segments of the microstrip lines connected by the adjacent two columns of microstrip antennas are opposite so that the N T / R components are arranged in a rectangular grid manner and the vertical distance between the center points of the adjacent two rows of T / R components is a second distance, the second distance being greater than the first distance. The invention increases the spacing between adjacent rows or adjacent columns of T / R components, in which control, cooling, power supply and other systems can be placed, so as to improve the heat dissipation effect of T / R components to a certain extent.

Description

technical field [0001] The present disclosure relates to the technical field of antennas, in particular to an active phased array antenna. Background technique [0002] With the rapid development of computer technology, digital-analog hybrid integrated circuit technology and microwave phase-shifting technology, active phased array technology has the advantages of multi-target, long-distance, high reliability and high adaptability, and is being transformed from radar to communication electronics, Development in multiple fields such as positioning and navigation. [0003] The radiation and phase of the T / R components in the active phased array antenna will change during long-term operation, and some T / R components will fail after long-term use. Therefore, in the active phased array antenna, it is necessary to monitor the T / R components in the array, and calibrate the amplitude and phase of the array in time, so as to ensure the consistency of the amplitude and phase of the an...
