Abstract

A dielectric antenna and an antenna module are provided. The dielectric antenna includes at least one dielectric unit. Each dielectric unit is separated into a first region and a second region, and the second region could have a bending portion. A conductor covers a surface of the second region of the dielectric unit to form a waveguide structure. The waveguide structure has a first endpoint connected to the first region and a second endpoint serving as a signal feeding terminal for feeding or receiving signals. The dielectric antenna can be packaged with a chip and thus is suitable for millimeter-wave high gain antenna modules.

Description

technical field [0001] The invention relates to an antenna technology, in particular to a dielectric antenna and an antenna module. Background technique [0002] Antennas are essential elements in wireless communications. With the increase in the demand for data transmission in wireless communication, the millimeter wave frequency band has a large available bandwidth, for example, the 60GHz frequency band can have a bandwidth of 7GHz, allowing various applications in communication. On the other hand, due to the advancement of semiconductor technology, the RF front-end single chip can be realized. Compared with the previous modules made of discrete components, the integrated chip can reduce the size of the module, reduce the complexity of assembly, reduce the cost, and provide the important function of beam switching. [0003] Taking millimeter wave as an example, due to the large transmission loss of 60GHz millimeter wave in the atmosphere, a large effective isotropically ...
