In this paper a dualband suspended microstrip right-angled isosceles triangular patch antenna is designed for use in microwave imaging system for breast cancer tumour detection. An approximate design equations are developed and validated by CST Microwave Studio’s simulated result. Here dual band operation is achieved by manipulating fundamental mode and higher mode of microstrip antenna. Tuning of this antenna is achieved at frequency 3.35 GHz and 6.70 GHz which shows high frequency ratio 2. This antenna shows good impedance matching, similar radiation pattern and polarization with broadside radiation pattern at both operating frequencies.
