Abstract:
In this research, a UWB antenna is designed for breast cancer detection. The
technology on which it works is microwave imaging. The frequency range is between
1.5GHz-6.5GHz spectrum which meets the requirements of our application that is
UWB antenna for tumour detection and other medical applications, especially for
breast cancer detection. The material used for fabrication is Rogers TMM 3 and the
tool in which the antenna design is simulated is FHSS. As to enhance the performance
of the antenna several modification and techniques are used i.e. slot insertion and
Bezier curve. This tends to improve the Gain, Return loss S11, Directivity and
radiation pattern of the system. To increase the total gain of the system a symmetric
array of size 2 x 5 of monopole pattern arrangement. This combination achieves better
results in terms of the target parameters as compare to the previous work that runs on
asymmetric array having hemispheric arrangement.
