Abstract

The invention discloses a miniaturized antenna based on a folded micro-strip line. The miniaturized antenna comprises a top layer, a middle floor layer and a bottom feeding layer arranged in turn fromtop to bottom. A dielectric layer is bonded between the top layer and the middle floor layer, and a dielectric layer is bonded between the middle floor layer and the bottom feeding layer. The top layer is a metal patch, and the patch body edge where the non-radiation side of the metal patch is located is etched to form multiple strip-shaped metal bands which constitute a folded band group. The free ends of the multiple strip-shaped metal bands are flush with the non-radiation side of the metal patch. The miniaturized antenna based on a folded micro-strip line achieves better radiation characteristic and more comprehensive performance, but also has the characteristics of high gain, wide radiation angle and low profile. Moreover, the miniaturized antenna is compact and easy to manufacture,can help to improve the performance of the communication system, and is of high practicability.

Description

technical field [0001] The invention relates to the field of microwave application technology, in particular to a miniaturized antenna based on a corrugated microstrip line. Background technique [0002] Microstrip antenna is a new type of antenna that has been gradually developed in the past thirty years. In recent years, in many microwave and antenna systems, due to its small size, light weight and low cost, miniaturized microstrip antennas are used in engineering applications. It is of great significance in the field, such as for the design of handheld wireless communication equipment and high-performance antenna arrays, etc., and has achieved a lot of results in the design method. [0003] Common microstrip antenna miniaturization techniques include loading short-circuit probes, slotting, using high dielectric constant dielectric plates, and using composite left and right hand structures. However, there are some defects in these technologies. Even if the miniaturization...
