For this application, MICROWAVE STUDIO[R] (MWS) from Computer Simulation Technology was chosen to simulate the DRHA.
Figure 6 presents the actual improvement in gain when compared with the traditional 200-MHz to 2-GHz DRHA.
Not only have we managed to get a much higher gain and better illumination pattern at the 2-GHz point, but the improvement at 2 GHz also opens the possibility for this 200-MHz to 2-GHz DRHA to be used to higher frequencies.
