Abstract

The invention discloses a multifrequency directional-diagram reconfigurable antenna based on double-open resonant ring, relates to an antenna, and specifically relates to a directional-diagram reconfigurable antenna so as to solve the problem that the existing reconfigurable antenna is complex in structure and can not operate simultaneously at multiple different operating frequencies. The reconfigurable antenna comprises a first metal sheet, a round metal-form feed wafer, a dielectric slab, four second metal sheets, four metal open resonant rings and eight switches, wherein a layer of metal sheets is attached to the lower surface of the dielectric slab, the round metal-form feed wafer is attached to the middle part of the upper surface of the dielectric slab, the four metal open resonant rings are arrayed around and attached to the periphery of the round metal-form feed wafer, each metal open resonant ring is of a circular concentric inside-outside dual-ring structure, and the opening of one inner ring of each metal open resonant ring is provided with a switch. The multifrequency directional-diagram reconfigurable antenna based on double-open resonant ring is applied to wireless communication systems.

Description

technical field [0001] The invention relates to an antenna, in particular to an antenna with a reconfigurable pattern. Background technique [0002] As a component used to transmit or receive radio waves, the antenna plays a pivotal role in the wireless communication system and is an indispensable part of the wireless communication system. With the rapid development of high-frequency satellite communication systems, radar, wireless communication systems, especially the construction of global 3G and 4G networks, the requirements for antennas are getting higher and higher. On the one hand, the antenna needs to be able to work in multiple frequency bands, have multiple working modes and have good transmission performance. On the other hand, it is necessary to reduce the weight of the antenna, reduce the volume of the antenna and reduce the cost. The main function of the antenna is divided into two aspects: on the one hand, the antenna can convert energy; on the other hand, th...
