Abstract

The present invention discloses a miniaturization broadband microstrip antenna, comprising a radiation patch configured to form two axially symmetric rectangular grooves along a narrow side direction on a rectangular patch, the radiation patch having a top and a bottom which have a same stair-stepping corner cut structure. An antenna constructed by the radiation patch with a rectangular gradual corner cut structure and an E-shaped grooving structure may only consist of the radiation patch, a dielectric slab, a metal floor and a probe. The radiation patch is located at the right side of the dielectric slab, the metal floor is located at the back side of the dielectric slab, and the probe is connected with the radiation patch through punching from one side of the metal floor. According to the invention, the flow direction of the microstrip antenna current is changed, and a plurality of resonance frequency points is increased, therefore broadband and miniaturization of the microstrip antenna are achieved.

Description

technical field [0001] The invention relates to an antenna in the field of wireless communication, in particular to a miniaturized broadband microstrip antenna. Background technique [0002] With the development of radio technology, the antenna is the front end of the radio frequency system, miniaturization and broadband work are the direction of its development. The current broadband antenna implementations mainly include frequency-independent antennas (helical antennas, log-periodic antennas), biconical antennas, V-cone antennas, TEM horn antennas, corrugated horn antennas, loaded antennas, and various deformation antennas. These antennas are widely used in practical projects. Due to their own structural limitations, they usually have problems such as oversized, complex structures, and inconvenient installation. At present, microstrip antennas can easily realize the miniaturization of the structure, but the broadband work generally requires additional corresponding measur...
