Abstract | 相控阵接收机是将小型阵列天线放置在射电望远镜焦平面位置,通过波束合成器瞬时形成多个交叠波束、实现连续视场覆盖的信号接收技术。作为阵列天线的一种,相控阵接收机前端的天线阵列由于各阵元排列紧密,阵元之间的电磁耦合在所难免。本文利用常规互阻抗法对四阵元微带天线阵列进行耦合效应分析,通过各端口开路电压及阻抗矩阵求解耦合电压,借此调整波束合成网络以实现阵列的去耦合功能。通过去耦前后的实测方向图比对,可以看到阵列的主波束方向、旁瓣电平及对称性都有了一定的改善,以此验证了该解耦技术的可行性。 |
Other Abstract | Phased array receiver is a signal receiving technology that places a small array antenna at the focal plane of the radio telescope, forms multiple overlapping beams instantaneously through a beamformer, and achieves continuous field of view coverage. As a type of array antenna, the antenna array at the front end of a phased array receiver is inevitably subject to electromagnetic coupling between the elements due to their close arrangement. In this paper, the conventional mutual impedance method is used to analyze the coupling effect of the 4-element microstrip antenna array. By comparing the measured pattern before and after decoupling, it can be seen that the main beam direction, sidelobe level, and symmetry of the array have been improved to some extent, which verifies the feasibility of this decoupling technology. |
