The invention discloses a dielectric resonator double-frequency antenna with the ground plane shaped like the Chinese character Shan. The antenna comprises a circular dielectric resonator block, a single-layer antenna dielectric substrate, a tennis racket-shaped metal surface, an arc strip-shaped metal surface and a metal surface which is shaped like the Chinese character Shan and positioned on the back surface of the antenna dielectric substrate and is grounded; the circular dielectric resonator block is adhered to the upper part of the front surface of the antenna dielectric substrate; the tennis-racket-shaped metal surface and the arc-shaped metal surface are located on the front surface of the antenna dielectric substrate, the tennis-racket-shaped metal surface comprises a straight-strip-shaped microstrip line and an annular microstrip line with gradual transition connection, and the arc-shaped metal surface is close to the annular microstrip line; the metal surface shaped like theChinese character Shan is located on the back surface of the antenna dielectric substrate, the left and right sides are provided with symmetrical deformation sharp-corner-shaped metal arms, and the middle part is provided with a straight-strip-shaped microstrip line. The antenna is small in size and simple in structure, can realize quasi-omnidirectional radiation, and can be integrated with a planar circuit.

Description

technical field [0001] The invention belongs to the field of antennas, and in particular relates to a dielectric resonator dual-frequency antenna with a mountain-shaped ground plane. Background technique [0002] Since the dielectric resonator antenna was proposed in the early 1980s, related technologies have advanced rapidly, and various dielectric resonator antennas have appeared. Due to the existence of various frequency standards in the communication field, the conventional single-band dielectric resonator antenna cannot meet the requirements of some multi-band communication application fields. With the development of multifunctional smart devices, multi-frequency or dual-frequency dielectric resonator antennas have become a research hotspot. A common way to achieve dual-band dielectric resonators is to excite the dielectric resonators by feeding power to two different dielectric resonators, so that each dielectric resonator generates a frequency band to generate dual-f...
