Early detection of Breast cancer aids in fast and effective treatment to save life. Mammography, which is currently the most popular method of breast screening, has some limitations. Microstrip antennas are used as alternative in growing medical application. The primary objective of the project is to design a simple and cost effective conformal Micro strip Patch Antenna with dimensions of 37 mm X 28 mm using FR4 substrate for operating frequency 2.45 GHz. For enhancing the bandwidth, directivity and gain, 4x1 antenna arrays are designed in linear with corporate feeding networks. Experimental results of proposed antenna are simulated and discussed using the ADS simulation software. The proposed antenna has a bandwidth of 65 MHz covering the frequency range 2.41-2.49 GHz, the return loss below -26 dB and antenna gain of 2.45 dB. The flexible patch antenna holds good efficiency of 87.1%. This paper proposes design patch antenna can be applied for early Breast tumor detection in women.
