| Abstract | 阵列天线是将单天线以一定的排列方式组成天线阵列，以此实现更高信号收发性能的装置。阵列天线作为一种高效的信号接收设备，被越来越多的应用于射电天文领域。随着射电天文对高灵敏度、超宽带、大视场等性能的追求，对阵列天线的各项指标也在不断攀升。耦合性是由于阵列天线各单元之间相互作用而产生的特殊效应。传统阵列天线阵元间隔一般都至少保持0.5倍的波长以降低耦合。本文设计并研制工作于1.25GHz下的窄带16阵元微带天线阵列，阵元间距为0.7倍的波长，通过S参数测试，独立阵元的回波损耗在-24dB以下，阵元间耦合性在E面方向上低于-32dB、在H面方向上低于-39.6dB，满足设计指标。后续工作将进一步开展该阵列天线的阻抗、方向图及交叉极化等性能测试。 |
| Other Abstract | Array antenna is a kind of device which composes single antenna array in a certain arrangement to achieve higher signal receiving and transmitting performance. As an efficient signal receiving device, array antenna is more and more used in the field of radio astronomy. With the pursuit of high sensitivity, ultra-wideband and wide field of view in radio astronomy, the performance of array antenna is increasing. Coupling is a special effect due to the interaction between elements of array antenna. In order to reduce the coupling, the spacing of traditional array antenna elements is usually kept at least 0.5 times of wavelength. In this paper, we design and develop a narrow band 16 elements microstrip antenna array working at 1.25 GHz. The spacing of the elements is 0.7 times of the wavelength. Through the S parameter test, the return loss of the independent elements is less than -24 dB, and the coupling between the elements is less than -32 dB in the E-plane direction and - 39.6 dB in the H-plane direction, which meets the design index. The impedance, pattern and cross polarization of the antenna array will be tested in the future. |
