引言在雷达、卫星通信和其它某些场合,副瓣的要求十分严格。由于天线元之间以及天线元通过馈电网络的互耦、天线阵的参数将受到很大影响。这一情况对毫米波微带天线阵更为突出,因而就提出了一体化设计的问题。这也就是说将天线和馈线作为一整体用矩量法求解实现给定电流分布的阵列的所有几何参数。这问题十分复杂。最近国外已有一体化分析的报导,但一体化设计和综合尚未见报导。作者提出了一个简化的方法。即将网络和天线去耦。引进等效网络的概念就可证明这种做法与一体化设计方法相等价。在求馈电端电压分布时,采用了逐次逼近的方法取得了更好的效果。
Introduction Radar, satellite communications and other occasions, the requirements of the side lobe is very strict. Due to the mutual coupling between the antenna elements and the antenna elements through the feed network, the parameters of the antenna array will be greatly affected. This situation is more prominent for the millimeter-wave microstrip antenna array, and thus put forward the issue of integrated design. This means that using the antenna and the feed line as a whole, all the geometrical parameters of the array that realizes a given current distribution are solved by the moment method. This problem is very complicated. Recently, there has been a comprehensive analysis of foreign reports, but integrated design and synthesis have not been reported. The author proposes a simplified method. Decouple the network from the antenna. The concept of introducing equivalent networks proves that this approach is equivalent to an integrated design approach. In seeking the terminal voltage distribution, using successive approximation method has achieved better results.
