Breast cancer is described as the abnormal development of cell tissues out of their boundaries. If not cured at early stage, it would prove to be deadly. A large group of women around the world is suffering from this problem. There are various methods used to detect early stage breast cancer. Amongst them, microwave imaging is found to be a safer method in many ways. This manuscript presents a rectangular, reduced DGS microstrip patch antenna to detect breast cancer. Method adopted to detect breast cancer is to compare the current densities, E-field, H-field, Gain, Return Loss etc., in breast model with and without tumor. Simulated results present a significant difference between these values and hence indicate the presence of tumor. The proposed rectangular patch antenna is designed with overall size of 40*57.98*1.6 mm3. This rectangular patch antenna with reduced DGS is resonating at 4.636 GHz and has return loss of -47.9791 dB, VSWR of 1.008 and antenna gain is 5.11dBi. With these specifications, proposed antenna can detect tumor of radius 3 mm, 2 mm and 1.5 mm.
