本人想做一个手机模型，但关于馈电的方法不熟悉啊，谢谢各位高手进来指点一下

本人现在做一个手机模型用来优化，模型如下图，关于馈电的叙述如下：
The folded loop strip has a uniform width of 0.5 mm and is arranged to be symmetric with respect to the central line of the system circuit board. One end (point A) of the folded loop strip is the feeding point of the antenna, which is at about the central line of the circuit board and is connected to a microstrip feedline printed on the front side of circuit board in this study. The other end (point B) of the folded loop strip is with a small gap of 1 mm to point A and is grounded to the system ground plane through a via-hole in the circuit board.
这里面我不太明白，图中a点连接50欧馈电线，馈电线的那一头两个波浪纹是什么意思啊?还有b点通过什么方式接到接地板啊?
希望高手指教啊，多谢！

（1）应该是长度没有定吧，看你具体把馈电点放在哪里。
（2）应该用过孔吧！
小编留言：
谢谢啊，那长度会影响到性能吗?采用同轴馈电或者是平行馈电效果会不同吗?

仿真的话，就用50欧姆的LUMP PORT设置在AB处就可以了
不嫌麻烦的话，你建一个50欧姆的同轴线模型馈电也没问题。
实际情况下，在同轴馈电基础上加一个巴伦，平衡馈电的效果会好很多！
这个LOOP天线调整走线宽度比例合适的话，能得到非常好的带宽！
我感觉馈电的平衡性能不太好，可以尝试用CPW的巴伦来馈电
多谢各位大侠
