摘要

A 2.4-GHz RFIC-on-chip antenna in 0.18 um CMOS 1p6M process is presented. The HFSS 3-D EM simulator is employed for design simulation. A printed 2.4GHz antenna has been realized by using the CMOS RFIC-on-chip. The measured VSWR is less than 2 from 2.4- to 2.483-GHz. The measured phase distribution of the input impedance is quite linear and the H-plane patterns are almost omnidirectional. The Kirchhoff's surface integral representation (KSIR) was adopted in the developed FDTD code to compute the far field distributions from the near filed ones in time-domain. For the biometry applications the investigation of the body effect on the antenna radiation characteristics is achieved. The human tissue includes single layer of muscle and three-layer tissue. Simulated results illustrate that the included current in fat layer is very small due to the lower dielectric constant and conductivity. After adding a floating metal, the absorbed energy of human tissue will be reduced. The chip area is 0.495 (0.75×0.66 mm2).
