Abstract

The invention relates to a magnetic dipole Yagi antenna based on a dielectric resonator, comprising: a dielectric substrate, a reflector, a feed network and a drive unit, the improvement of which is that the drive unit is a rectangular dielectric resonator, and the feed network is used for Coplanar dual wires excited by differential signals, which directly feed the drive unit. The dielectric resonator of the present invention is excited by coplanar double lines, and is excited to generate TE 11δ The dielectric resonator for the mode electric field is a magnetic dipole. Since the radiating unit adopts a rectangular dielectric resonator, the antenna proposed by the present invention has the advantages of small size and high gain compared with the traditional metal Yagi antenna. In addition, the three-dimensional dimensions of the dielectric resonator can be adjusted according to the actual system requirements, which demonstrates the flexibility of this design.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a magnetic dipole Yagi antenna based on a dielectric resonator. Background technique [0002] Yagi antenna is a typical parasitic element antenna, which is widely used in modern communication systems. In the past few decades, various Yagi antennas based on electric dipoles or magnetic dipoles have been researched and fabricated. Electric dipoles of different shapes whose length is half the wavelength of the operating frequency are widely used in the above-mentioned antennas. Those three-element Yagi antennas that use electric dipoles typically provide 4.5 to 6dBi of gain. If these Yagi antennas want to continue to increase the gain, they need to add more directors, but this will make the size of the antenna bulky. At the same time, the lateral dimension of these antennas is 0.5 wavelength of the operating frequency, which limits the application of these antennas...
