The invention discloses a millimeter wave dual-band micro-strip antenna which at least includes a rectangular patch. The rectangular patch is provided with a ring-shaped slot in the upper left and a ring-shaped slot in the lower left, with the ring width of one ring-shaped slot greater than the ring width of the other. The rectangular patch is provided with a rectangular slot in the upper edge anda rectangular slot in the lower edge, the two rectangular slots are distributed symmetrically, and the midpoints of the rectangular slots are consistent with the midpoints of the upper and lower edges. The rectangular patch is further provided with two L-shaped slots. According to the millimeter wave dual-band micro-strip antenna provided by the invention, a diagonal ring slotting mode and an L-shaped slotting mode are adopted on the patch by using a gap loading mode and a patch slotting technology in order to extend the bandwidth. The whole patch slotting model is of a symmetrical structure.Impedance matching is achieved by adjusting the size of the diagonal ring. The bandwidth of the antenna is effectively extended.
Description
technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a millimeter-wave dual-frequency microstrip antenna. Background technique [0002] In the field of wireless communication technology, millimeter wave technology and space technology have promoted the development of low-profile antennas. Because millimeter waves have the advantages of high resolution and wide frequency bandwidth, millimeter waves will be widely used in future 5G communication systems. One of the application methods of millimeter waves in communication systems is the microstrip antenna. Compared with traditional antennas, microstrip antennas have been widely used in miniaturized, highly integrated and low-cost wireless communication systems due to their unique advantages. [0003] The microstrip antenna has the following advantages: first, the profile is low, that is, the size of the antenna is small, and it is easy to integrate on the ...
