Abstract: This paper presents a more improved method to characterise the breast tissue by employing a unique microstrip antenna. The pattern of the proposed antenna consists of a radiating patch with a rectangular slot, three stubs, a feed-line and a partial ground plane. Several parameters are used to analyse the microstrip antenna. The antenna designed provides a wide usable frequency band range from 2.4-4.76 GHz. In order to observe the interaction between the antenna and breast tissue, a heterogeneous breast model having dielectric characteristics similar to the human tissue is used. The tumour in the breast tissue is analysed by measuring the resonant frequency of the reflected signal. The results show that the shift in resonant frequency decreases as the size of tumour increases due to dielectric variation in the breast tissue.
