Abstract

The invention discloses a dual-band miniaturized microstrip antenna based on a split ring resonator, and belongs to the technical field of antennas. The antenna comprises a radiation portion, a dielectric substrate, a grounding plate and a feed line, the radiation portion is arranged on the dielectric substrate and comprises the metal split ring resonator and a metal radiation sticker, the metal split ring resonator encircles the metal radiation sticker in a non-contacting manner, the center of the metal radiation sticker is arranged on a symmetric line of the metal split ring resonator and not positioned at the center of the metal split ring resonator, the grounding plate is parallelly arranged under the dielectric substrate at intervals, the feed line comprises an inner core wire and a shielding layer, and the exposed inner core wire at the upper end of the feed line penetrates the grounding plate and the dielectric substrate and is connected with the metal radiation sticker. The dual-band miniaturized microstrip antenna has the advantages of high radiation efficiency and gain, simple and compact structure and low production cost.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-band miniaturized microstrip antenna based on a split resonant ring. Background technique [0002] In recent years, with the continuous development of wireless communication technology, people's requirements for the antenna design of the radio frequency front-end are constantly improving. Microstrip antennas are favored by antenna engineers due to the advantages of low fabrication cost, light weight, high mechanical performance, and easy conformality with other components. The miniaturization design of the microstrip antenna has always been the goal pursued by the industry. Generally, for traditional microstrip antennas, effective methods such as loading lumped elements, slotting, and meandering are usually used to realize the miniaturization of the antenna. However, these technologies severely limit the antenna's radiation performance such as bandwidth, efficiency, and...
