Very compact UWB antenna with group delay improvement
In this paper, very compact (12mm×17mm) and simple UWB antenna is proposed. The achieved bandwidth of the presented antenna is from 3.05 GHz to 12.5 GHz and in the most of the bandwidth, the return loss is less than -20dB. In addition to frequency characteristics, time characteristics such...

| description |
In this paper, very compact (12mm×17mm) and simple UWB antenna is proposed.
The achieved bandwidth of the presented antenna is from 3.05 GHz to 12.5 GHz
and in the most of the bandwidth, the return loss is less than -20dB. In
addition to frequency characteristics, time characteristics such as group
delay variations for three different antenna positions, namely, front to
front, back to back and side by side using CST MW studio are simulated and
discussed. To improve the group delay variations, by changing the radius of
the circle on the back side of the antenna, the antenna gain in different
frequencies will be tuned, therefore, the time domain characteristics of the
proposed antenna are greatly improved. |
