In present era antenna is playing a prominent role in biomedical engineering for improving health and quality of life. Pacemakers, deep neural implants, endoscopy, magnetic resonance imaging, microwave imaging and clinical instruments for thermal ablation are some examples of health care instruments which are taking the benefits of antenna and wireless body area network. Antennas can be implanted, placed on body and swallowed to transfer diagnosis information from the human body to the external monitor and further to thedoctor or concern person through internet. In addition, variation in the electrical parameter of antenna like near field electromagnetic radiations, impedance, reflection coefficient can be analyzed to detect diseases non-invasively. Breast and brain tumour detection, cancer detection and motion detection are some of the important applications of antennas. Moreover, heating effect of electromagnetic field is also valuable to treat the malignant cell tissues. In this survey paper, authors have covered all the possible application of antenna and the challenges faced by antenna designers to make them suitable for specific application.
