Integrated RFIC on-chip and GPS antenna with human body for wrist and wearable communication applications

Abstract

A GPS and Miracast 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 1.575GHz and 2.4GHz antenna has been realized by using the CMOS RFIC-on-chip. The measured VSWR is less than 2 from 1.575GHz and 2.4- to 2.483-GHz. This propose super quadric combo antenna in free space, electromagnetic coupling between super quadric antenna and human body and rectangular antenna for wrist watch type wireless communication applications. The measured phase distribution of the input impedance is quite linear and the H-plane patterns are almost omnidirectional and field tried GPS integration. In addition, in order to improve the way controlling this provide switch by software, a novel circuit structure which will control antenna pattern switching automatically by hardware is also developed for wireless healthcare and mobile biomedical application. RFIC-on-chip GPS and Miracast antenna also merger T/R-Switch design on single chip solution for 2.4GHz CMOS transceiver RF front-end. The old man can monitor healthcare and transfer to health center or passive devices by Miracast with software and show GPS location for wearable ambulatory application.
