Abstract

The embodiment of the invention discloses an optical transparent antenna, and the antenna comprises a three-layer structure which is formed by the sequential connection of a first layer, a second layer and a third layer. The first layer is an antenna radiator layer, the second layer is a dielectric layer with transparency, and the third layer is an antenna ground layer. The antenna radiator layer takes an ITO (indium tin oxide) film as a radiation paster, and the antenna ground layer employs a slotting-type frequency selection surface structure. According to the scheme of the invention, the frequency selection surface is a slotting type, so the frequency selection surface belongs to a band-pass frequency selection surface from the aspect of frequency attributes, the interior of a pass-band can achieve the reflection of an incident electromagnetic wave and the exterior of the pass-band displays transmission characteristics. Moreover, the frequency selection characteristics of the frequency selection surface enable the antenna to show directional characteristics when the antenna works at a pass-band of the frequency selection surface. Meanwhile, the slotting-type frequency selection surface is higher in light transmissivity. Therefore, the antenna solves a problem that an optical transparent antenna cannot achieve directional radiation in the prior art.

Description

technical field [0001] The invention relates to the field of wireless communication applications, in particular to an optically transparent antenna. Background technique [0002] With the rapid development of the wireless communication system, the application scenarios of the wireless communication system are becoming more and more abundant, so that the wireless communication system has more and more diverse requirements for antenna performance. In order to achieve good conformality, safety and stealth of the antenna so that it can be integrated in mobile terminals, satellites, automobiles and other systems that require antennas to have optical transparency, scientists have begun to pay attention to optically transparent antennas. [0003] In 1997, scientists from the National Aeronautics and Space Administration (NASA) proposed the idea of ​​using light-transparent film materials to make antennas. In 2000, the research team of N. Outaleb of Rennes 1 University in France to...
