| Summary: | Breast cancer is the most diagnosed cancer
among women all over the world after skin cancer. Meanwhile,
electromagnetic imaging has been a prominent detection
technique for biomedical diagnosis in recent years. However, the
electromagnetic imaging is struggling with the spatial resolution
that can be solved by an imaging technique based on the antenna
with a wide operating bandwidth at the higher frequency range.
In this paper, a printable Coplanar Waveguide (CPW)-fed
microstrip rectangular patch antenna with a wide – 10 dB
bandwidth of 18.7 GHz has been proposed for a breast cancer
imaging application. This printable antenna, after being
designed on a flexible substrate and simulated, operates from 21
GHz to 39.7 GHz which covers the millimeter-wave frequencies.
The antenna has achieved an average gain of 4 dBi with an
average radiation efficiency of over 80% for the entire -10 dB
bandwidth. The bidirectional radiation pattern of the antenna
offers the freedom of placing the antenna both at the front and
back position on the body surface. Moreover, a compact area of
5×5 mm2 makes the antenna suitable for the biomedical imaging
application at mm-wave frequencies by utilizing a low-cost
manufacturing process. |
