Abstract

Our goal is to develop THz module on chip to visualize bone grinding at
the early stage so that arthritis can be visualized and treated early. A critical
component of such module is antenna. A compact 4 by 4 beamforming
antenna array for biomedical application is presented in this paper. We
are proposing a novel antenna which is in the form of a circular ribbon
shape with a gold patch. Gold material for the patch is used to enhance its
conductivity and to cut down backward radiation. Differential port pin used
to increase the bandwidth. Au-posts are finally used for output connection.
The proposed antenna operates over the frequency band from 201 GHz to
more than 228 GHz. Directivity and gain of the proposed antenna are 13
dB and 7 dB respectively. This makes it applicable for imaging systems
because of the frequency band for biomedical imaging. Index Terms—
Beamforming antenna, antenna array, Advanced design system (ADS),
Biomedical imaging.

Keywords:
