WEARABLE MICROSTRIP ANTENNA WITH DEFECTED GROUND STRUCTURE FOR BREAST CANCER DETECTION
Keywords:

A wearable antenna application has been spread in many fields including a solution in the medical application. One of their application in the medical field is the detection of breast cancer in the human body. This paper reports the microstrip antenna for breast cancer detection at a frequency of 2.46 GHz made from wearables material. The proximity coupled and the addition of a defected ground structure to the ground plane is used to get the wider bandwidth. Detection of breast cancer is performed by using breast modeling or breast phantom.
The dimensions of the designed antenna are 39 mm x 46.5 mm and realized using Rogers RT6006 material. Based on the results of simulations that have been done, the antenna has a return loss value ≤ -40.28 dB and a VSWR value ≤ 1.01. The antenna can detect cancer based on the different properties of materials in the breast phantom which affects changes in the value of S11 parameters.
Based on the simulation, if the size of the cancer is getting bigger, then the value of return loss obtained increases or headed to 0 dB. The value of return loss caused by the differences in electromagnetic absorption of different cancer material.
