Abstract :
In this paper, the energy pattern of various UWB antennas will be studied by the impulse time domain radar system. The UWB antennas will include omni directional antenna, directional antenna, and high directivity antenna array. They are discussed in the following sections. Energy patterns of UWB antenna and its measurement system with impulse time domain radar is described in this paper. Three radiation energy patterns have been presented for the two kinds of UWB antennas and UWB antenna array. The time response waveform for antennas depends on geometry of antenna and EM incident directions. Detail of discussion will be presented.
