This paper is all about to design an antenna for brain tumor detection using a novel material Kapton polyimide. A brain tumor, which has the potential to spread throughout the body and result in cancer, is one of the worst disorders. Using a novel material and observing variation in the S1,1 parameter to spot brain cancers is the main objective of this paper. An on-body microstrip patch antenna constructed in the K band and a three-size brain tumor in a brain phantom model were employed to identify the existence of brain tumor. This antenna can operate between 4 and 14 GHz. The resonance frequency of the proposed antenna was discovered to be 12.96 GHz in free space. A VSWR of 1.00 and −92.06 dB S1,1 was also measured in this area. S1,1 is −49.93 dB at 8.58 GHz in the Normal Brain and −40.51 dB at 11.87 GHz in the Tumor Affected Brain.

In this paper, A standardized and implantable planar inverted f antenna is accomplished with modified design, featuring balanced size miniaturization for wireless communications. This antenna has an intensified reliability and feasibility in turns for performing for biomedical application. The proposed antenna is represented For MICS BAND. MICS band contains 402 to 405 MHz resonant frequency. This band has been chosen because of its tractability towards higher bandwidth with the decreasing size of the antenna. 12.5 × 12.5mm2 miniature dimension is offered this antenna. The antenna is observed a better resonant performance at different substrate material. Four different types of substrate materials as Rogers RO3010, Rogers RT3210, Rogers RT6010 and Alumina were used in order to design the antenna to observe which one yields a better performance for the desired antenna. The purpose of using those comparisons is to find the lowest return loss and also get an acceptable efficiency which causes the higher gain in the desired. antenna. Return losses, Radiation Patterns, S-Parameters is observed and analyzed the antenna performances by using CST Microwave Studio.

Early detection of breast cancer can be a life-saving measure for many patients. The inaccessibility of X-rays, magnetic resonance imaging (MRI), and other medical facilities in many resource-constrained areas hinders the early detection of breast cancer. In this paper, the use of a rectangular patch antenna for breast cancer detection is proposed by using multiwall carbon nanotubes (MWCNTs) as patch material. The proposed antenna is designed by CST software which is (30 × 40 × 1.66) mm in dimension. A breast model is designed including tumor and cancerous tumors by specific tissue properties for observing the antenna performance in different cases. In free space, the return loss of the designed antenna is observed at −33.414 dB. Moreover, the S11 is examined in a normal breast, a breast including a normal tumor, and a breast including a cancerous tumor is −32.641 dB, −34.94 dB, and −35.22 dB respectively. It can be utilized on a human body phantom model due to its adaptability and reduced radiation properties. The proposed antenna is miniature in size, cost-effective, easily portable, and eco-friendly. It can be used as a first screening tool for breast cancer patients, particularly in resource-constrained regions.
