The invention provides a dielectric substrate integrated dielectric resonator antenna, which comprises a dielectric substrate and a reflecting metal plate, wherein the dielectric substrate is stepped; the dielectric substrate comprises a first dielectric block and a second dielectric block; the first dielectric block and the second dielectric block are cuboid; the second dielectric block is formed on the front of the first dielectric block; a rectangular hole is arranged in the reflecting metal plate; the reflecting metal plate covers the front of the first dielectric block and exposes the second dielectric block through the rectangular hole. The dielectric substrate integrated dielectric resonator antenna is designed on one dielectric substrate without adopting other media to design, so that the antenna and a feed structure can be designed on one dielectric substrate, the seamless integration of the antenna and the feed structure is realized, and the antenna has the beneficial effects of high positional accuracy and small integration loss and is especially suitable for millimeter wave application.
Description
technical field [0001] The invention relates to the field of microwave technology, in particular to a dielectric substrate integrated dielectric resonator antenna. Background technique [0002] The dielectric substrate integrated dielectric resonator antenna has the characteristics of low profile and light weight. At the same time, compared with the transmission line antenna, its characteristics such as low conductor loss and zero surface wave loss make this type of antenna particularly suitable for use in millimeter wave wireless communication systems. [0003] However, the dielectric substrate integrated dielectric resonator antenna also has certain defects, which makes it difficult to be used in millimeter wave applications. Usually, the medium used to design the dielectric substrate integrated dielectric resonator antenna uses a high dielectric constant medium, so as to improve the radiation efficiency while reducing the volume. The structure used to feed the dielectri...
