Problems solved by technology

The CMOS process uses silicon as the substrate. The low resistivity (10 Ω·cm) and low electron mobility of silicon greatly consume the electromagnetic energy of the antenna, resulting in low gain and radiation efficiency of the antenna, which cannot meet the short-term requirements. Technical index requirements for distance wireless communication

Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] figure 1 It is a 3D diagram of a regular hexagonal AMC structural unit based on CMOS technology. By using the waveguide transmission method for analyzing the periodically loaded structure and the simulation design of the 3D electromagnetic simulation software Ansoft HFSS, it can be equivalent to using a vertically incident plane wave to excite a periodic structural unit. By changing the side length a of the regular hexagonal AMC structure unit and the gap width g between the units, it can be obtained image 3 The reflection phase diagram of the regular hexagonal AMC structural unit shown, at this time a=107 um, g=45 um, and the reflection phase is ±90 o The corresponding frequencies are 52.3 GHz and 67.8 GHz, respectively, and the reflection phase gap completely covers the license-free frequency band of about 7 GHz (57-64 GHz) near 60 GHz. figure 2 It is a top vie...

Abstract

The invention relates to a 60GHz on-chip antenna based on an artificial magnetic conductor structure. The 60GHz on-chip antenna comprises a silicon substrate layer, a SiO2 layer and a SiN layer from bottom to top and is characterized in that the SiO2 layer comprises six metal layers, the six metal layers are sequentially M1 to M6 metal layers from bottom to top, a triangle monopole antenna is arranged at the M6 metal layer of the SiO2 layer, a regular hexagon artificial magnetic conductor structure which is loaded periodically and based on CMOS (Complementary Metal Oxide Semiconductors) process is arranged at the M1 metal layer of the SiO2 layer, and the triangle monopole antenna adopts 50 Omega coplanar waveguide to feed. By the 60GHz on-chip antenna based on the artificial magnetic conductor structure, the reflection phase of a vertical incident wave at 60GHz is zero, the reflection phase band gap completely covers freely-licensed frequency band about 7GHz around 60GHz (57-64GHz), and meanwhile, the gain, the radiation efficiency and the like of the on-chip antenna can be effectively improved.

Description

technical field [0001] The invention belongs to the field of antenna technology and wireless communication, and relates to a 60 GHz on-chip antenna based on an artificial magnetic conductor structure. Background technique [0002] The artificial magnetic conductor is the AMC (Artificial Magnetic Conductor) structure, which is a kind of metamaterial. It has the similar properties of the ideal magnetic conductor. Through reasonable design, it can achieve the same phase reflection characteristics of a certain frequency point to the vertically incident plane wave. [0003] The 60 GHz on-chip antenna based on CMOS technology has gradually become a research hotspot in short-distance wireless communication due to the advantages of low cost and large-scale production of CMOS technology, as well as many advantages of 60 GHz spectrum. The CMOS process uses silicon as the substrate. The low resistivity (10 Ω·cm) and low electron mobility of silicon greatly consume the electromagnetic e...
