报告摘要：

For a long time, transparent antennas have been of planar (2D) structures, which are based on the theory of patch antenna. Very recently, 3D transparent antennas have also been developed. This is a rather new and attractive topic. The principle of 3D transparent antenna is based on the theory of dielectric resonator antenna (DRA); the resonance is caused by the whole 3D structure rather than a confined cavity as found in the patch-antenna case. The basic characteristics of glass DRA will be elucidated through the design of a hemispherical glass DRA. This glass DRA has been used as a focusing lens for a solar-cell panel, and the results of both the antenna and solar-cell panel parts will be shown. 

Today, many modern buildings have antennas installed for indoor wireless communications. By using transparent DRAs as covers of the light, the antenna and lighting systems can be combined into one. Their installations can be done in one go, reducing the overall installation work and cost of the two systems. Also, since the light-cover DRA simply appears as part of the lighting system, it is an excellent camouflage antenna. Different light-cover DRAs will be given in this talk.

3D transparent antennas can also be designed as aesthetic glass wares or artworks. This idea is especially useful when invisible antennas are needed due to psychological reasons. The results of the aesthetic glass antennas will be presented. Finally, glass antennas for other applications will be discussed in this talk.
