关于蝶形宽带微带天线的设计
索引:蝶形宽带微带天线. 设计方案 排列效率
摘要:现在提出一种基于绝缘体衬底的有限长度的宽带微带天线的设计方法。这种方法快速、对计算精度要求较低,是建立在一蝶形天线进行二等分而形成的两个梯形天线的 。首先设计出单边的梯形部分,然后制作出相同的另一部分并在其顶点处将其连接。与理论计算相比在X波段上实验测量表现得很好。其有效带宽达到10.6%。
(One approach to an antenna book starts with a discussion of how antennas radiate. Beginning with Maxwell’s equations, we derive electromagnetic waves. After that lengthy discussion, which contains a lot of mathematics, we discuss how these waves excite currents on conductors. The second half of the story is that currents radiate and produce electromagnetic waves. You may already have studied that subject, or if you wish to further your background, consult books on electromagnetics.The study of electromagnetics gives insight into the mathematics describing antenna radiation and provides the rigor to prevent mistakes. We skip the discussion of those equations and move directly to practical aspects. )

今年计算机学院研究生入学复试分多个小组。现在老师需要知道每组复试同学中男生和女生的人数。请你编写程序分别统计出男女生的总人数。
Input
输入的第一行是一个数t(0 < t < 10),表示有t组测试用例。
对于每组输入数据有两行,第一行是一个正整数n(1 < n < 1000),表示参加该组复试的总人数。接下来一行有n个整数(取值为0或1),0代表男生,1代表女生,整数间由一个空格隔开。
Output
对于每组测试用例,输出一行,由两个数组成,用一个空格隔开,分别表示男生和女生的总人数。
