Description

technical field [0001] The invention belongs to the field of wireless communication, and specifically refers to a broadband high-gain millimeter wave dielectric resonant antenna array. Background technique [0002] With the rapid development of wireless communication technology, the functions of wireless communication electronic equipment are becoming more and more abundant. Electronic equipment has filled every corner of people's lives. It is also getting higher and higher; but the capacity of the current communication system is difficult to meet the growing demand for data transmission. At the same time, with the rapid development of integrated circuits, the size of the instrument is getting smaller and smaller, and the space left for other components will become smaller and smaller. Therefore, miniaturization, broadband, circular polarization, high gains and many other requirements. [0003] As a resonant antenna, the dielectric resonator is a pure dielectric material w...
