| 摘 要： | 为提高微带天线的整体性能，设计了16元矩形微带平面天线阵。该天线阵采用串并联馈电网络，辅以四级四功分器对各微带阵元同相馈电，保证馈电幅度、相位为等幅同相。利用阻抗变换对天线阻抗加以匹配，并以4×4均匀平面阵，确保天线发射场的方向垂直于天线阵平面。CST仿真结果表明：要求频率内，16元矩形微带平面天线阵的回波损耗在10dB以下，z轴的方向性良好，最大增益可达15．89dB，满足天线的性能要求。

| Abstract: | A sixteen-unit rectangular microstrip antenna array is designed to improve the overall performance of microstrip antenna. The antenna array is designed with feed network consisting of serieswound network and shunt-wound network, supplemented by four four-unit splitters, to excite the microstrip antenna array in the same phase so that each unit of the microstrip antenna is excited in the same phase and range. In the feed network, the antenna impedance is matched by impedance change and a 4 × 4 plane array is so designed that the direction of the launch is perpendicular to the antenna array panel. The result simulation by CST shows that in the required frequencies, the sixteen-unit ree crostrip antenna array which boasts the return loss of less than 10 dB, better direction-sense and the highest gain of 15.89 dB is up to desired performance of the antenna. tangular miin the z-axis |
