| The radiator, reflector plate and the feeder equipment of the planar circular disc monopole were placed on the same plate. The special structure reduced the spatial volume, and was used to realize the miniaturization of the antenna. Detailed exploration was conducted to determine the antenna′ s properties. Through simulations and experiments, it was demonstrated that the antenna has good ultrawide-band performance. At the meantime, the antenna′ s height was further reduced by cutting a certain length, puckering a certain length or rotating a certain angle to realize miniaturization. The influence of novel antennas’structure parameters on performance was discussed and the return loss and radiation patterns of the antennas were presented. Simulation and experimental results showed that the novel antenna can performance requirement in ultrawide-band. The novel antennas have good application prospects in satellite and mobile communication systems. |
