  antenna bandwidth
Important parameters of antennas, such as antenna bandwidth, radiation waveform and cross coupling determine the GPR system performance.
      
A further enhancement of the antenna bandwidth is also achieved using 100-μm capacitive coupling between the feed and the antenna strip.
      
First, we developed a metamaterial substrate with arbitrary material composition and subject to a pre-specified antenna bandwidth enhancement.
      
In the presented approach, by using the genetic algorithm (GA) based on fuzzy decision-making, some modifications have been implemented to the incorporated slots which lead to even more enhancement in the antenna bandwidth.
      
A representative plot of the antenna bandwidth calculated at Zmag = 8,700 Ohms for the different applied strain states is shown in Figure 6.
