Novel electric small size meander-line microstrip antenna

Abstract

The invention discloses a novel electric small size meander-line microstrip antenna which comprises a dielectric substrate and a sheetmetal, wherein the upper surface of the dielectric substrate is provided with a metal sticker which is in the shape of a jagged meander line, the lower surface of the dielectric is also provided with a metal sticker, the area of the metal sticker is S, and the area of the sheetmetal is S1. The novel electric small size meander-line microstrip antenna has the advantage of having better antenna performance indicators.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a novel electrically small-sized meander line microstrip antenna. Background technique [0002] Electrically small size: An object whose linear dimension is much smaller than the wavelength. [0003] Microstrip antenna: On a thin dielectric substrate, one side is coated with a thin metal layer as a grounding plate, and the other side is made of a metal patch with a certain shape by photolithography, and the patch is fed by a microstrip line or a coaxial probe. Antenna made of electricity. [0004] For electrically small-sized microstrip antennas, miniaturized antenna technology is usually used in order to reduce the size. The miniaturization techniques of microstrip antennas are as follows: [0005] (1) Improve the dielectric constant of the dielectric substrate; [0006] (2) meandering flow technology; [0007] (3) Short-circuit loading technology; [0008] (4) additio...

AI Technical Summary

Problems solved by technology

[0012] For an electrically small-sized microstrip antenna, due to the limited space for adjustment, the range of size parameter changes is small, and the range of performance parameters to be adjusted is also limited accordingly.

Therefore, the disadvantage of the prior art is that the scope for adjusting the performance of the antenna is limited
