The antenna comprises a first dielectric substrate, a second dielectric substrate, a metal floor with two slits, a feed network with two input ports and six rectangular radiation patches, wherein the first dielectric substrate and the second dielectric substrate are sequentially stacked from bottom to top, the metal floor is located on the upper surface of the first dielectric substrate, and the feed network is located on the lower surface of the first dielectric substrate; the six rectangular radiation patches are located on the upper surface of the second dielectric substrate and carry out coupled feeding according to the two slits. The antenna has the advantages of wide impedance bandwidth, wide radiation bandwidth, simple structure, low cost, directional diagram and the like.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to a novel multi-mode broadband pattern diversity microstrip antenna. Background technique [0002] In the research and design of antennas, it has become an important research direction to improve the quality of antenna transmission and reception and enhance the efficiency of spectrum use. Diversity technology can improve channel reliability while reducing the impact of multipath fading without increasing signal transmission power, and is widely used in communication systems. Diversity antenna, because it has the performance of two or more antennas at the same time, can be used for transmission and reception of wireless channels at the same time, so as to alleviate the fading effect, improve channel capacity and spectrum efficiency, and meet the needs of different services for high data rates . There are three basic diversity antennas, namely space diversity, polarization div...
