Abstract

The invention discloses a broadband patch antenna based on differential resonator feeding, which comprises a metal base plate, an L-shaped folded sheet located above the metal base plate, and a radiation patch arranged on the top of the L-shaped folded sheet and parallel to the metal base plate , the dielectric substrate that is attached to the lower surface of the metal base plate, the resonant unit formed on the dielectric substrate and the feeder connected to the resonant unit, and one of the horizontal folded surfaces of the L-shaped folded sheet passes through the metal vertically through the metal probe. The bottom plate, the dielectric substrate and the resonant unit are connected. The present invention uses differential feeding to reduce the cross-polarization of the antenna, and works in four resonant modes, the bandwidth reaches 63.7%, and the height of the antenna profile is only 0.158 vacuum wavelengths; with flat gain and stable radiation pattern.

Description

【Technical field】 [0001] The invention belongs to the technical field of communication, in particular to a broadband patch antenna based on differential resonator feeding. 【Background technique】 [0002] In recent years, with the rapid development of wireless communication and increasingly complex application scenarios, the bandwidth and other performance requirements of antennas in wireless communication systems are getting higher and higher. Microstrip patch antennas are widely used in various wireless communications due to their advantages of low profile, light weight, easy processing and low cost. [0003] However, one disadvantage of microstrip patch antennas is that they have a relatively narrow bandwidth, making them difficult to apply in broadband communications. Many broadband techniques have been studied over the years in an attempt to increase the bandwidth of microstrip antennas. In the existing technical solutions, some add parasitic patches in the horizontal ...
