Abstract
Now, we study for autonomous Unmanned Aerial Vehicle (UAV). In this study, it is necessary to keep watching the position of UAV by using computer system above ground at all time. But we must build communication systems which get extensive positioning data of UAV. So, we designed "antenna for detecting position of data" to realize these systems. This report is showed that we could design the Modified Transmission Line Antenna (MTLA) by introducing the concept for the high levels of gain on monadelphous antenna, and it arrayed these MTLA in a vertical direction.
