Microwave Breast Cancer Imaging Technique: Arrangement and Parametric Analysis of Array of Flexible Microwave Antennas with Phantom

X-Rays mammography is widely used in the world for diagnosis of Breast cancer. Unfortunately, mammography is usually failed to diagnose at early stages. Microwave imaging (MWI) technique is non-hazardous and efficient for breast cancer screening and diagnosis at all stages but still is an under-developed technique. In present studies, the key features are studied for development of MWI. Microwave (MW) antenna radiates and receives signals to or from nearby scattering objects exactly like the technique of a radar. Flexible MW antennas of 2.1 GHz frequency are designed because of penetration through the skin is greater in this frequency range but the resolution is quite low therefore an array of 8 antennas are used to improve the resolution. Mutual coupling (MC), gain, and directivity of split patch antennas are studied here. Antennas arranged at 1800 t each other are MC because these produce equal of greater than -20dB difference of s-parameters of S(X,1) and S(Y,1). The gain of MW antennas with tumor is very low as compare to communication antennas but using an array of same antennas the gain increases. All these parameters help to develop and improve the wearable device of MWI.
