The narrow bandwidth property of a microstrip antenna is one of the important reasons to restrict its wide application.

微带天线的窄频特性是限制它广泛应用的原因之一。

Helical antenna has not only almost identical to the resistive input impedance in broad bandwidth, but also works by the end of super-gain front lobed map in the same frequency band.

螺旋天线不仅在宽频带上具有近乎一致的电阻性输入阻抗，而且在同样的频带上按超增益端射阵的波瓣图工作。

The high-bandwidth antenna that aims back at Earth is beaming back "lots and lots of data" and the rover is expected to capture a color panorama of its surroundings on Thursday, she said.
