Design Patch Antenna at Wi-Fi Applications for Detection Breast Cancer Tumors

The development in the science of communications technology in the medical fields has led to the use of patch antennas for applications in biomedical applications and for the Wi-Fi band, which ensures reliable results for detecting tumors. Antenna is deliberate using Rojers R03203 with 0.75 mm for thickness of the substrate and 3.02 for the permittivity. The actual size of this antenna is (36⋅58 ⋅0.75) mm. For the patient's health safety, the patch antenna was designed at the frequency of WiFi applications and placed above the human breast phantom, which was designed with two homogeneous layers, skin and fat, with different electrical properties, and all of these designs and simulations were done by Microwave Studio cst 2021. The designed antenna displays the current density, electric field, standing wave ratio, specific absorption ratio, and return loss. Through changing these elements during the simulation, it was observed that there was a small tumor in the imaginary breast the first time and two tumors the second time.
