Ultra wide-band antenna having uni-directional radiation pattern characteristic

摘要

The UWB antenna having a radiation pattern in one direction (uni-directional radiation pattern) is disclosed. The UWB antenna is excited (excitation, 勵 起) by the electromagnetic energy power supply, substrate, are produced on the upper surface of the substrate through the whole class that receives the external electromagnetic energy, power feeding to one side and the other side direction of the substrate active loop radiating element to the dipole radiator (dipole radiator) for emitting an electromagnetic wave, and, excited by the electromagnetic energy feed via the feed section, whereby each of constructive and destructive to the electromagnetic wave to be emitted to one side and the other side direction of the substrate by the dipole radiator and a (active loop radiator). Accordingly, it is possible to implement the UWB antenna with one-way radiation pattern with small. ; UWB antenna, dipole radiating elements, an active loop radiating element, one-way radiation pattern
