同时，一般的微带天线的带宽比较窄，在1 ~ 5%。
And the standard microstrip antenna has a very narrow bandwidth of 1 ~ 5%.
为了展宽天线的带宽，采用双层圆形贴片电磁耦合天线。
A two layer electromagnetic coupled circular patch microstrip antenna is adopted to widen the frequency band of the antenna.
因此天线的带宽和Q 综值之间的关系在当时的确是个没有搞清楚的问题。
The common expression for bandwidth in terms of 1/Q is neither logical nor helpful in clear exposition.
